I had a friend group at my old job, thought it was going really well. They stopped hanging with me, replaced me with someone else. I would ask them if the vibe was off, if everything was okay, and they'd always say "yeah everything's fine, you should just reach out we'd hang" but I didn't want to beg for their friendship. 

Then I got a new job and so did they. One of them still works at that job, and I occasionally see her when I visit (it's an animal shelter I volunteer at now).

Finally after one of them got married and they all got to go except me. I got upset having to once again see photos of them hanging out having fun so I decided to unfriend them from Facebook. Within 24 hours one of them messaged me and asked why I unfriended her and if "everything is alright" (?!?!?), and when I was honest that it hurt to see them post photos without me and needed a break from that, she said that it was because I often made conversations about me, changed subjects, and interrupted. All great feedback I would have loved to have when I directly asked if i was doing anything wrong.

....so, that's how my interpersonal life is going I guess.
