My boyfriend accused me of rape but he said yes?

Female here so a week ago i told my boyfriend i don't know how to trust him because he had sex me with me after multiple times of me saying no and he still did it, right after I told him this he said that when he was at mine the one time i asked for sex i raped him and made him feel really uncomfortable, even though i asked him if he wanted sex and he said yes and i said are you sure and he said yes again he didn't seem uncomfortable at all.

I feel so messed up and i don't know what to do any advice is appreciated?
