Wasn’t going to post but honestly the confusion of it all has been eating away at me. Let’s call the person B. B and I were close friends a few years back. B was someone I’d consider pulling me down, encouraging drinking and distracting from exams etc. We were getting on best when I was In a very toxic relationship and flunking all my exams. When I quit that relationship and started myself on a better year, I noticed their behaviour turned and became very bitchy, lots of strange comments a “friend” wouldn’t be making such as insults about my social media, new flat, etc. I reached breaking point one drunken weekend and told her not to come back to my flat she was staying at. Since then we’ve not been friends, had the odd message. B happened to be at a mutual friends bday recently, I was dreading how awkward it would be but they were back to normal convo, jokes about the past , went out for a smoke with me , bought and accepted a drink off me, talked about having nights out in future and said the past was in the past. I asked multiple times that night if I could add them back on fb, to which they said yes. The friend request was never accepted. I get not wanting to be friends again, but why act so split at the weekend? It’s so odd , I don’t know if it’s something purposeful she’s enjoying or she has a personality disorder because it doesn’t make sense
