I have no one to complain to about this and I'm just... blargh. It's unreasonable of me, I'm not asking anyone to make me feel justified, it just sucks.
DH and his brothers are very close, so we see them a few times a week at least. His older brother is a little crazy, but I've gotten used to him.
Problem comes in that earlier this year he and his amazing girlfriend (who all of us loved and who was really good for him) broke up. I'm still friends with her: we just clicked and became really close and I know she wishes it wasn't over, which by itself makes things a little hard. Since BIL changed his relationship status on FB, one of his exes has been sniffing around (tagging him in everything, posting lyrics from love songs to his timeline), and now it's looking like he and this other chick might get back together.
Now all of that's *his* business but: BIL has no friends in relationships except DH and I, so I know he's going to want all of us to hang out as couples... I don't want this. Aside from me wishing things could go back to the way they were for almost two years, I cannot stand this other girl. She and BIL were only together for 3 months before, and they made each other miserable. She is a pretentious hipster b*tch, and I don't usually say that kind of thing about someone. She really, really, is.
How long can I plead a headache to dinner plans before it gets suspicious?
