I need opinions, maybe past experiences???

me & my boyfriend were doing things & i was giving him head but it got soft. we’ve been having a lot of sex lately but we did it once on friday he was kinda drunk so he blamed it on the fact that we were using a condom, on saturday we did do it a couple of times & he said he had to tap out. yesterday I gave him a few hand jobs & he came but not a lot, he blamed it on the fact that it was tired & needed a lil bit of a break, is that really a reason?? or should i be concerned that he’s not into me anymore
