This is complicated.

I would suggest counselling - either one each or together. It sounds like he resents you and you need to explore why, with a safety net, it should not be about blame. You need to look after yourself - increase your self-esteem. The sex you describe sounds very one-sided and almost aggressive, 30 minutes of oral, followed by facial cum...and then "tough luck.." Does this guy love you? I think it is a question to ask, someone who loves you should not do this to you.

Good luck, and keep posting, we all support you here
