I agree with Marie123 that a restorative justice letter helps, but I wouldn’t share with your abuser. I didn’t since I knew the main culprit (my sister) would enjoy reading it knowing how much damage she has caused me mentally and physically and how much power she still has over me. I think some of us become targets. We get in an abusive relationship that would breakdown our self esteem and confidence to such an extent that others will see us as a target and then it becomes a vicious cycle. We become everyone’s floor mat. If people closer to us stopped it earlier on instead of blaming us or play down the issue, things could have been different.
I found therapy very helpful. Meeting a trusted therapist who can walk you through the recovery process is very helpful.
