It's likely coercive control when a pattern of monitoring, rules, isolation, and threats keeps shrinking your freedom, and you change what you say and do to avoid your partner's reaction. The pattern matters more than any one fight.
Often, no. When one partner uses coercive control, couples therapy can make things less safe, and many domestic violence experts recommend individual support first. Therapy can't balance power that one person holds, and what you share may be punished later.
Missing someone who hurt you is common, and it makes sense. Relationships that mix harm with affection can create a strong bond, and your nervous system can crave the good moments even when you know the relationship wasn't safe. Missing them doesn't mean you should go back.
Yes. Therapy can help you grieve the people and community you lost, untangle the fear and shame that came with leaving, and rebuild a life on your own terms. You don't have to decide what you believe now to start.
EMDR can be used safely with complex PTSD when it's paced carefully. That usually means a longer preparation phase to build stability and coping skills before processing painful memories, with you able to pause or slow down at any point.
