People are taking the word "friend" way too loosely. You can be friendly, you can be polite, but being someone's friend would mean you'd need to actually know the person on a deeper level which she doesn't, and didn't bother to until he asked her to hang out. She's missing out on some friends hanging out. Not the whole group. Not all the time. For the three... Wow are you in your head. I'm a girl too, and if a guy asked me to hang out my first thought wouldn't be "he wants to fuck me" because guess what? People can hang out without wanting to fuck you. How entitled to attention do you need to be to assume that every guy that asks you to hang out (not on a date) wants something to do with you sexually? Crush is a fleeting thing, and he wanted to get to know her first to even decide if he wanted to date her to begin with. They clearly never hung out one on one before. She has a full right to reject him to a hangout, i dont fault her there. But if she was told later then by her friend that it would be a good idea to skip hanging out at his place for a bit to have things settle, she should've not shown up. Other people that she's friends with didn't show up for that hangout where she was clinging to him either, so obviously the friend group isn't just concentrated there. She's excluded from coming to his house because she rejected to even get to know him better and hang out with him and OP wanted time to process. Maybe he wanted to drink the rejection away with his friends that weekend and she rubbed it in even worse. Lastly, she isn't fuck zoned. OP kept it civil and didn't speak uo next 2 times she showed up uninvited. There wouldn't even be an issue if she just offered for the group to hang out someplace else, or if she didn't latch onto the girl OP brought later and annoyed her. He doesn't need to stop hosting, people should realize that there's nuances to things, that as bad of communication skills OP has, still, her behavior wasn't correct. It's not about rejection even at this point. If i was in a friend group and the party host whom i dont know well but am friendly with asked me out and i rejected him, and then saw i wasnt invited in the group chat where everyone is, id cordially give it a week or two for dust to settle. Put two and two together and hang out with other people, given that her friends Tyler and Jenn weren't even there at the party where she was clingy. She won't lose her friends and die if she doesn't go to 2/3 pool parties.
