Is OTHER wrong in the post ? POST : Am on Mobile.

I have few redeeming qualities, one of those being that I give some good advice. I enjoy doing it as I feel I can help someone out, I get a dose of dopamine, and they get a new perspective or, hopefully, a solution. 

However, there are these two girls, that I would consider friends (one of which more than the other but thats another story). I've had periods of time where I would consistently snap, or chat one of these girls at the beginning of our friendship, before everything eventually mellowed out. But there was a turning point.

Girl 1, or M from now on, is someone who... hurt me, (not purposefully... Hopefully) but I still made the effort to remain her friend and I'd like to think I did a good job. Every once in awhile we'd chat about something, and before long I noticed a pattern. Every conversation would im some way wrap around to a problem of hers, be it about boys or friends, I mean I aided her rapidly decaying relationship with her mom. Its been awhile since she's even talked to me and frankly I'm bitter, she doesn't owe me a conversation or friendship but goddamn, I feel used.

Girl 2 is to a much lesser extent, but the two girls are friends and I've had to help them stay that way before. She snaps me everyday several times a day, and even askef me how her prom dress looked last night. So I feel much better about our friendship.

Reddit AITA for being upset and a little bitter, at this situation, enough that I want to cut contact with M?
