I feel so mean

My boyfriend came into the room last night after a while of staying up without me and told me "I want you to do things to Me" and I was asleep so I said "what kind of things" or something I don't really remember but it was in a mean way and he rolled over to his other side and didn't say anything lol I was like half asleep though!!! We haven't really had sex since finding out at 4 weeks and I'm 6 weeks today. What should I do to excite him now? I feel like I owe him!! The last time we did it though after finding out I had light pink spotting so I think that scared me. And I honestly haven't felt 100% great lately so that could be why I haven't wanted to have sex either.
