I sort of understand where you're coming from. With my ex, that wasn't the exact case but he put pressure on me to do things like that, so in the end I gave in without wanting to do stuff.
I think in your case it was rape, you didn't want to do those things and he continued, especially with the BJ, where he wouldn't let you answer before shoving it in your mouth! I think you should tell your mom :/ or a close friend to help you say it to someone, and of course, you should break up. You're with an agressor and you're afraid of him!
Darken, imo she's afraid of saying no :/ Unfortunately, it happens and you find yourself stuck there just agreeing to things to avoid a confrontation.
