advice please

I was molested when I was 7 years old by my mother's boyfriend's sister. She was 13.

It really has haunted me my entire life. I am now 36.

My mother and father got back together when I was turning 8. She got pregnant with my little sister and my parents got married.

FAST FORWARD

My mom and dad got divorced and guess what, she went back to her ex from 1993. 😫 the same man who's sister molested me. I was devastated.

I never told my mom about what happened to me. I put it behind me and kept that inside

Now I would have to see her again...I felt so low when I seen her after idk how many years.

She played it like hey neicy Pooh. bs. Like bitchhh I remember what you used to do to me and make me do to you!!

I had to tell my mom. She moved in with him.. in the exact same building where it happened to me in. He owns the building. His sister lives next door and his mother downstairs.

I just can't go over there...I feel so bad because I don't want my mom to think I don't love her or want to see her. But that building gives me nothing but bad memories.

I remember crying for my dad and my grandmother many nights. 😢

I finally told my mom. She was so upset and told me that she cut his sister off!. She was calling my mom sister and being so fake but whole time touched on me and I was so young. I feel like I should have told my mom but I was scared I didn't know I just wanted to be her friend. She used my innocence.

My mom is still with the guy and it bothers me. I don't know what to do

any advice please 🙏🏾
