Input: This may be unnecessarily long. So I've been best friends with this girl since i was in 4th grade (going on 11 years now) and she was the very first friend I have ever made. We were basically inseparable for most of our lives until I decided that I wanted to go to university in the UK with my (now ex) GF. I've always felt used and just unappreciated but was so terrible at making friends that I didn't really think about it until I got close with my roommates here and they have told me that this girl is in no way my friend. I had a really good think about all the things that have happened over the years and it just confused me more. One of the things that has bothered me immensely is the fact that right before I left the states my best friend and another friend had a girl, who they had never met in person before, move in with them. I could see why, the girl was in need of a place to stay and they were willing to share the space, that wasn't what the problem was. My problem was that they treated this girl about 10000x better than they ever treated me. For this girls birthday they got her a pet cat, Gucci, makeup, clothes, etc. So much stuff, and they have never been to a single one of my birthday parties. Not a single one. I've never had a friend at my birthday party, at my graduation party, going away party, nothing. I had back surgery and asked if she would let my family pick her up to visit me because I was so lonely and she didn't want to. They've known this girl for less than a year and they're already living with her and giving her everything she wants. They've given me gifts, but they're all joke gifts, like broken cds from goodwill. I don't care about the monetary value of gifts, id rather just not be treated like a joke. I'm about to sound like an asshole probably but my family majorly supported this girls family. We would give her mom at least 2 grand every christmas and we paid her to do random shit all the time because she was a single mom and struggling with kids and a sick sister. For christmas I convinced my family to give her a company phone (which was a samsung galaxy not some shit company phone) since she didnt have one and an Ipad, she never thanked us really and gave it away  to a girl that racked up 70+ GBs on it sexting her 50 year old pedo boyfriend. These are things that i really easily looked over before. I never really thought about them as negative things it was just whatever.

The thing I'm really mad about is that she never messages me, like ever. She has said many times that she is bad at texting and she doesn't like talking over the phone, which I totally understand, but now I don't see her for months at a time and cant see her irl. I would message 7-8 times with no response for days and when i would get a response it was one worded and disinterested. I would usually only get a message from her if i went on a drunken suicidal rant on twitter then passed out, but even then its probably just hi. She messaged me a few days ago and instead of messaging back right away like I usually do I have been ignoring her messages. Shes started tagging me in posts about 'best friends' now and its pissed me off more than anything so I'm continuing to ignore her. I'm sick of wondering if I have been getting leeched off of and actually have no actual importance to, who I thought was, my only friend in the world, or if I'm an overly sensitive brat. Sorry this is so long.

AITA?

wanting to cut off ties with my best friend because she wont come to my bday
