I went into college with one of my best friends from high school. There was a group of three friends we both started hanging out with a month before our summer began. Last Monday I wasn't doing anything all day. I got called into work very last minute for 5 o'clock so I said yes because I had no other plans. The moment I stepped out to the front at work I saw two of the girls we had started hanging it with and said hi. One of them was like "oh your friend (not gonna add names) and ___ are just over there. I didn't invite you because ___ (my friend) said you were hanging out with your boyfriend tonight" and I just replied with "oh I don't know why she would think that." I was immediately upset because this is something that always happens to me. I always am the one to be forgotten or left out and it sucks. A few minutes later my friend and the other girl showed up to talk to me. I just ignored my friend by serving customers and doing dishes in the back until she left. Usually I just laugh it off or pretend I don't care but this time I was mad. In fact I remember shaking so much that I messed up an ice cream cone because I was going to stand up for myself for once. I didn't want to have this conversation while I was at work though so that's why I ignored her. She's recently texted me asking me why I'm so mad and that she doesn't know what she did wrong. She started guessing and tried to say that their plans to hang out were very last minute and she just assumed I was busy so she didn't bother asking. Turns out they went out to lunch so I could have attended that because I was free all day. They only went to the mall briefly afterwards and that's when I saw them (I work in the mall). I don't know if I'm right to be mad. I just feel like I've let her walk all over me and I'm not taking it anymore. Too be completely honest I wouldn't even care if we weren't friends anymore, this has been going on so long that I just don't care for her. But our class has 16 girls and I have two years left so being or her friend or at least friendly is mandatory. I just don't know what to do about it. And leaving me out isn't the only thing she does. She's constantly being rude to me. Just saying rude comments. I remember one time our friend in high school curled her hair and was really excited about it and she told her that it looked childish and she should fix it. She also hates my boyfriend who is one of the nicest people on the planet. He's never done anything to give her a reason not to like him. The first time I introduced him she straight up said to his face that he looked like a rat, so he's never liked her either but at least he's got a reason. She's also told me to cheat on him and insults our relationship all of the time when there's nothing to insult. There was one time when she was talking to a guy for about a week and he called her beautiful or something and she showed me and went, I bet your boyfriend doesn't even say stuff like this. And I told her that he did and she didn't believe it and acted like her one week relationship (which ended shortly after) was somehow superior to my 2 1/2 year relationship. She also just makes comments here and there, like bashing my hair, or my makeup, or even my phone case, which doesn't seem like much but when she does it as often as she does it adds up and I end up feeling really upset about it. One thing I can't stand is that she always bashes my taste in music when she plugs in MY phone into MY car. I listen to a lot of old/classic music and she gets all salty because I'm not into rap and her weird techno rave music. And when she says it every single day of my life, yeah it bothers me. I just don't know what to do anymore. I can't stand her but I'm stuck with her.
