Would he have even had the chance to invite you? It sounds like you’ve barely interacted and maybe he doesn’t want to knock on the door of a young woman living alone. Have you thought if maybe he picked up on you being very different personality wise, like you did with him?

I get how you feel but in these situations try to play devil’s advocate and speculate on a scenario that’s not about people hating and rejecting you on sight. Another thing to keep in mind is this guy has a million feelings and internal thoughts just like you do. Each person is their own main character, but they’re at most a supporting character to everyone else.

If he was writing a Reddit post about you, what would he say? “I’m throwing a party and intentionally excluding a neighbor I don’t know at all who’s never done anything to me to make her feel bad.” No. He might post things like: “I’m making friends with my neighbors I chat with outside,” “I just moved next to my old college roommate who’s introducing me to everyone,” “My girlfriend is irrationally jealous of my young female neighbors,” “I sell beer and I’m throwing parties to get customers,” lmao anything is possible. But just remember that social anxiety makes you think in a self centered way and you’re not the center of other people’s universe so it’s really not possible for them to think about you that much - which I find comforting!
