I'm still angry

I was sexually abused by my husband's father (wasn't my husband at the time obviously) at 13 to the age of 15 (never raped) I finally confronted him a few months ago... I am nearly 20... he apologized for it... I thought if I ever heard him say he was sorry I'd feel better and like I got what I needed. What I deserved. I thought I'd be able to move on. But I am still angry... in fact I think his apology made my anger and mental health WORST!!! I am now lost as to what to do... btw no one on my husband's side believes me apart from my husband and his mother says she is standing by her husband... it's all getting to much
