Input: I'm sorry if this is so confusing. I've made up a few names to talk about who's involved in this situation. I'm 19 and have a cousin 1 year older called Mary. A few weeks ago Mary was asked out by Joe. Joe  later said it was stupid of him to ask her out because he doesn't have any feelings towards her and he just jumped the gun because they had so much in common. She rejected him, of course. But now she says it's super awkward and she hates him. By the way she acts it feels like Joe is Romeo pondering over his lost love and crying at night over Mary's rejection, but he truly doesn't seem to care and still considers her a good mate and has nothing but nice things to say about her, though she tells me she goes out of her way to avoid him. He actually asked me out as well. I rejected him too (although I might actually see what dating him is like since I do fancy him and only rejected him because my cousin told me I had to) I guess he's just desperate for a girlfriend. Anyway me and my mates are going to a local concert next Thursday and my best mate and I asked him to come as well which he said yeah. But Mary, who also planned to go is super pissed at me. She says it'll be so awkward because he asked her out and he's practically her "ex" that we're choosing him over her. I told her she can uninvite him if she truly wants but she said no, I should be the one to do it. I told her to grow up, but now I feel guilty because I feel like I am choosing him over her. Should I uninvite him? AITA for hanging out with him?
