AITA for wanting to cut off my friends?

  Please forgive the format of the text, I am currently using the mobile app. 
  I (19F) have 2 high school friends I’ll call them Amy (19F) and Mary (18F). We recently went off to college but I tried to stay in contact.
  Amy and Mary are both studying in the same city, while I went to a school out of state. My birthday is today and everyone but them wished me a happy birthday. Amy had also had a birthday a bit ago and Mary made a whole post for her exactly at midnight, but neither of them have congratulated me. 
   This might be petty but there’s been a lot that’s been leading me to want to cut them off. Throughout high school they were always hanging out without me, I tried to make plans but they always fell through. When I made my choice to go to an out of state school, I told them to let me know when they are free so we can set up a time to hang out. They never texted me and even when I double texted our group chat, they ignored me. I was very hurt but tried not to make a huge deal out of it since I was moving soon. They also made plans in front of me and when we did eventually hang out, they would make inside jokes about their hangouts without me. I constantly defended Mary when she had a falling out with her best friend (who I also was in a bigger friend group with), and lost many friends because I stood by her alongside Amy. I regret defending her because now thinking about it, I think Mary was jealous that our friend was having the high school relationship Mary wanted while she never had a boyfriend. I honestly think it stemmed from jealousy. I did apologize for defending Mary to our friend and we ended up reconciling. 
     I don’t know if I am being dramatic, I honestly probably am. I had expressed to them many times how I wanted to hang out with them as much as possible before I left but again, they would rather hang out with each other. I think I feel more hurt because I also had a bad experience with another trio and had told them before about how much it hurts to be left out. Now that I am thinking about it they don’t know much about me because they never asked. 
      So, AITA for wanting to cut off my friends because they constantly forget about me?
