me and my boyfriend have been datong 10 months. but this situation happened at around 6 months and i just cant let it go. long story short

i was staying at his house, and i woke up to him with is dick inside me watching hentai and fucking me.

i felt like a sex toy and all trus was gone. the reason i stayed with him is becuse i thought i qould get over it but i cant. i love him and all but every now and then i feel resentment. what should i do, no judgement please
