Complex PTSD, trust & relationships
If people were where the hurt came from, closeness can feel scary. Safe connection can be learned, one small step at a time.
By the numbers
What research says about complex trauma, relationships and change.
Complex trauma
Change is possible
Why closeness can feel risky
When harm came from people, the body learns to be careful with people.
The VA’s National Center for PTSD describes significant difficulty sustaining emotional closeness as one of the three extra areas of complex PTSD. Cleveland Clinic describes severe difficulty forming and keeping meaningful relationships.
This makes sense. Complex trauma often happens inside relationships, with a parent, partner or someone in charge. The body learns that closeness can lead to harm. This guide goes deeper than the PTSD & relationships guide, which covers PTSD in general.

Cleveland Clinic links disorganized attachment to abuse, trauma or neglect. It can look like wanting love but fearing it, pulling close then pushing away.

Feeling on guard and watching for danger is a core part of PTSD and complex PTSD. In relationships, it can mean reading a lot into a pause, a look or a short text.
Old feelings can rush in through an emotional flashback, making a small moment feel like abandonment or attack.

The fawn response means trying to appease a threat to avoid harm. In relationships it can look like people-pleasing and giving in.
The Complex PTSD, shame & self-worth guide explores the fawn response in depth.

Some people with complex trauma keep others at arm’s length. Others hold on tight, fearing being left. Both are ways of trying to stay safe.
Attachment fears: pulling close, pushing away
Fear of being left, fear of being trapped, and the swing between them.
Attachment is the bond we form with the people who care for us. When early care was unsafe or unpredictable, it can shape how we love and trust as adults. The Attachment, love & intimacy guide explains attachment styles in detail.
Read more
Anxious attachment is often linked to care that was sometimes warm and sometimes not. Later, it can show up as fear of being left and needing reassurance.
What can help
- Asking directly for reassurance, instead of testing
- Noticing the gap between the fear and the facts
- Self-soothing skills while you wait for a reply
- Telling a partner what helps you feel secure
Read more
Avoidant attachment is often linked to little emotional support. Later, it can show up as strong independence and discomfort with closeness.
What can help
- Naming the urge to leave before acting on it
- Noticing that closeness and freedom can exist together
- Sharing one small feeling at a time
- Taking space, and saying when you’ll come back

Disorganized attachment is often linked to abuse, trauma or neglect. People may want love but fear it, pulling close then pushing away.
Read more
A study following more than 4,000 people found that some life experiences led to lasting changes in attachment. How people made sense of those experiences mattered too.
Cleveland Clinic notes that change starts with noticing your patterns, then slowly reshaping them, often with a therapist and safe relationships.
Rebuilding trust, slowly
Trust is built in small pieces, through actions over time.
After complex trauma, trust often can’t be given all at once. It can be built gradually, by watching whether people’s actions match their words. Trustworthiness and transparency is one of the six principles of trauma-informed care.

A slow trust ladder
- Share something small, like a preference or opinion.
- Notice how they respond. Do they listen? Respect it?
- If it went well, share something a little more personal.
- If it didn’t, you can step back. That is information, not failure.
Read more
In a healthy relationship, the National Domestic Violence Hotline says, you believe what your partner says and don’t feel the need to keep “proving” trustworthiness. You talk openly and listen to each other.
Signs to look for
- They do what they say they will
- They keep your private things private
- They respect your need for time and space
- They stay kind when you disagree
Read more
An emotional flashback can make a safe person suddenly feel unsafe. The feeling is real, but it may belong to the past.
Questions to check
- Can I ask them about it, calmly, later?
- Has this person given me real reasons not to trust them?
- Is this feeling the right size for what happened?
- What would I tell a friend in this situation?
Read more
Not every broken trust can or should be repaired. If someone keeps harming you, protecting yourself is not a failure to trust.
The Betrayal & rebuilding trust guide covers repair after betrayal in more depth.
Safe or just familiar?
Why unsafe patterns can feel like home, and how to notice the difference.
Patterns from early life can shape who we are drawn to, often without us noticing. Something that feels familiar can feel “right,” even when it isn’t good for us.

If you grew up with unpredictable care, a calm, steady person may feel boring at first, while an up-and-down relationship feels exciting. That pull is learned, and it can be unlearned.
Read more
Healthy signs
- Honest, while still allowing some privacy
- Open about problems, and willing to listen
- Respectful of time and space apart
- Trusting, without needing proof all the time
Read more
Things to take seriously
- Discouraging you from seeing friends or family, or getting very jealous of time apart
- Insulting, shaming or putting you down, especially in front of others
- Intimidating looks, actions or threats
- Making your decisions for you, like about work or school
- Pressuring you into sex, alcohol or drugs
The Hotline notes that many abusive people seem like ideal partners at first, and that even one or two of these signs is a red flag. It offers free, confidential support 24/7.
Boundaries in close relationships
Boundaries make closeness safer, not smaller.
Cleveland Clinic describes physical, emotional and time boundaries. They protect your space, your feelings and your availability. Healthy boundaries are not selfish.
Read more
Physical boundaries protect your personal space and comfort, like telling a date you are not ready to spend the night.
After trauma, some touch may feel unsafe even with someone you love. The PTSD & relationships guide covers closeness, touch and sex in more depth.
Read more
Emotional boundaries protect your feelings and mental health, such as limiting conversations you don’t want to have.
Phrases to try
- “I need a break. Can we come back to this tonight?”
- “I’m not ready to talk about that yet.”
- “Please don’t raise your voice with me.”
Read more
Cleveland Clinic suggests being specific, using “I” statements, following through, and starting with small boundaries to build confidence.
Friendships
Making and keeping friends when trust is hard.
Friendships can feel lower-stakes than romance, which makes them a good place to practise trust. They can also feel confusing if you never learned how friendships work.
Read more
Low-pressure places to meet people
- A class or hobby group
- A faith or community group
- A peer support group
- Volunteering
The VA recommends peer support groups for people living with PTSD. They can be a place to meet people who understand.
Read more
Old feelings of being left out can rush back when a friend cancels or goes quiet. Checking the facts before reacting can protect the friendship.
Before you react
- Ask kindly instead of assuming
- Give it a day before deciding what it means
- Ground yourself first
- Think of other reasons they might be quiet
Read more
If you tend to please people, you may give a lot and ask for little. Letting friends support you can feel scary, but it builds closeness.
Dating and new relationships
Going at your pace, and deciding what to share and when.
Dating with complex PTSD can stir up hope and fear at the same time. Going slowly, knowing your boundaries and having support outside the relationship can help. The Dating & new relationships guide covers dating in general.
Read more
You are allowed to say what you are and aren’t comfortable with, physically and emotionally. A healthy partner will respect that.
Read more
How others react when you share trauma matters. A 2019 review found that negative reactions, like blame or taking control, were linked to worse mental health.
Things to consider
- Watch how they handle it before sharing more
- You can say “I’ll tell you more when I’m ready”
- You can share how it affects you now, without sharing details
- You can test with something small first
Read more
Respecting each other’s time apart is a sign of a healthy relationship. Keeping friends, therapy and your own routines protects you and the relationship.
If your partner has complex PTSD
Understanding what you see, helping without losing yourself.
Loving someone with complex PTSD can be rewarding and hard. When you understand that some reactions come from trauma, it can be easier not to take them personally. The PTSD & relationships guide covers partners’ needs in depth.
Read more
The VA notes that when family members don’t understand that behaviour comes from PTSD, they may think their loved one is unhappy with them.
Pulling close then pushing away can be a survival pattern learned long ago.
Read more
Things that help
- Ask before touching or hugging when they seem on edge
- Do what you say you will
- Give a heads-up about changes of plan
- Offer choices instead of deciding for them
- Stay calm and kind during flashbacks

A therapist can be the first safe relationship, and teach skills for others.
A 2019 review of 51 trials found that CBT, exposure therapy and EMDR had moderate or larger effects on relationship difficulties in people with complex trauma symptoms.
