Kinda wanna stop being friends...

Ok so, I have this friend. We "dated" in middle school and she broke up with me because her parents made her and we didn't talk for YEARS! Until junior year when we had classes together (I had just transferred to that school and didn't know anybody else). 

But she just makes me so angry sometimes. I can never disagree with her on anything or else she just shuts down and won't talk to me. I said I didn't like TX2 (because he steals songs and basically told a "hater" to off themself in one, plus his new stuff is just ragebait) and she turned it into an argument and then just wouldn't talk to me the rest of the day. Over a music artist! Or if I tell her not to do something. Like, I get really bad intrusive thoughts and I was venting because I was so scared they would get worse when my step mom had her baby. AND SHE MADE A JOKE ABOUT IT! I told her that I don't really appreciate jokes like that about my intrusive thoughts and told her not to do that again and she just kept trying to excuse it. Eventually she just stopped talking to me again. Like, I was trying to set a boundary and you just keep making excuses saying you didn't actually cross the boundary in the first place? TF?

Then there's her shitty BF. The guy does NOT like me. He completely ignores my existence, even the few times we've met in person. She is totally obsessed with him though to the point it's actually concerning to me. She stays with him every weekend and is late to school because of it (He lives an hour away) and whenever he calls she drops everything to talk to him. Like, she'll stop mid conversation with me and our other friend just because her boyfriend calls and then completely ignores us. We also went to a concert recently, we were both super excited. But the day before I asked if she was excited for the concert and she just said she was more excited to see her BF even though she sees him and talks to him 24/7. THEN, at the actual concert I went up to go talk to her (We didn't go together or anything) and she just completely brushed me off! She didn't even talk to me, she just did the awkward smile and nod thing. I'm also pretty he's lying about his age, because she said he was 19 when they met but almost a year later she was getting him a gift for his 19th birthday, he also looks like he's in his 20's. He's also just an asshole, and both me and my friend are pretty sure he's gonna end up baby trapping her once she moves in with him. Hell, even my mom and my auntie got bad vibes from him. He also makes homophobic and racist jokes! Like girl, both your bestfriends are queer and our other friend is hispanic!

And we never even hang out anymore. She'll drag me to pick something up from the store with her, but as soon as I ask if we can drop by real quick or hang out for awhile she acts like it's the biggest inconvenience in the world. Even if she doesn't have anything else to do that day.

I also do tarot and both times I've asked about my friend ships my cards have said I have someone sucking my energy out and that I desperately need to let someone go (Among other things), and I truly believe in my cards (They've never failed me before).

The problem is that I rely on her. I don't have anyone I can talk to about certain things or get advice from, plus she literally drives me to and from school (Mostly). But at the same time, I almost feel like I'm using her, because I desperately want to get away from her but I still need things from her before I do that. And I do care about her, she's one of my best friends and I don't want anything to happen to her. I wanna keep an eye on her and be there when her bf inevitably does something shitty (Because he will) and I want her to be ok.

I think I'm just gonna stick with her for now, and reevaluate our friendship once we graduate in 2 months.
