Abusive relationship

I have been stuck in a shit relationship for a while now.. and I hate sleeping with her. You know when someone has hurt you so many times ..

it's hard to get out of it.. but whenever she saids something sexual or we have sex I just want it to be over.. I never get horny or anything .. I hate kissing her and her touching me.. I can't take it anymore.

Has anyone else been in this situation?
