Blamed for getting sexually assaulted (TW)

Hi guys so this is a repost and I’m sorry about that . But I’m looking for someone to talk to me about this I have no one. Basically I was sexual assaulted back in last year (my first semester of college) by a male that was much bigger than me and he touched me inappropriately when I shook my head no he continued to touch my breasts etc...

So I dealt with that happening and just acted as it was normal and brushed it off and I felt bad for calling the authority’s about it. I finally went home and then my step dad started kissing my cheek and hitting/kicking my ass and I freeze every time it happens (my mom and him don’t know about the sexual assault thing) so last night I got the guts to tell her along with her bf or whatever touching me and she got offensive saying it’s my fault blah blah blah.. basically victim blaming and belittling me for all of my flaws which had nothing to do with it.

And after I told her about the sexual assault thing and she said “even if a guy touches your knee and you don’t want it it’s assault” so her bf touching my ass is okay ??? And one time her bf said “your boyfriend will be mad” after touching my ass. And my mom is excusing it because she hasn’t seen it .

Hopefully I’m moving out soon..
