So confused.

So, I’m confused. Normally when I wake up my boyfriend, he gets up and goes to our bed and goes back to being lovey. But, tonight we were cuddling on the couch while I watched my show and he fell asleep.. I was tracing his lips gently with my finger for some reason and he shoved me away and told me to get away from him and then continued to sleep. That kind of hurt but I assumed that it probably tickled or something. But still. Then I tried to wake him a while later so that he could go to the bed and he just said stop in his sleep, so I’m letting him be now. But I don’t get why he’s like this now? (P.s. he likes me to wake him when I go to bed so that he can too, I’ve left him before for the night, and he said I should’ve woke him) is he just too tired? Is there more to it probably? Usually he doesn’t even remember stuff from his sleep, like when he’s sexual and what not.
