I think he should have voiced that opinion before they clearly talked about going on vacation together. My point being is I'm not going to sit the fuck around at home because the only person left going is a girl my friend went out with before. Although I've never dated a friends ex or anything of the sort I've seen a lot worse happen than he's talking about. lol And besides, I'm not a ''bro'', bro.
I told him when he asked me if i would get upset and i said yes..he knew before hand.
