Should I feel bad?

Me and my boyfriend are going on a romantic trip for 2 nights with another couple.

But lately my boyfriend and I have been arguing a lot and he hasn't been very nice so I don't really feel like having sex with him. I feel bad though since my friends bf has been calling it a "sextastic weekend" and all that. Also me and my boyfriend haven't had sex in more than a month 😕😕

I feel guilty cause I'm probably not gonna put out :/ I love him a lot but it's just been constant arguing idk what should I do..

I hardly lip kiss him too cause I hate saliva 😭😭 I feel like such an awful gf..

We have been together almost 8 months and we were long distance but he moved here and left his family to be with me and im not even physically pleasuring him ahhh
