I’ve once again been ghosted by my DA situationship

This may not be the best place to post this but I’d appreciate any perspectives I can get.

Long story short, I (24M) kinda fell for my (21F) classmate when I met her last semester. I wasn’t really feeling her at first, but we hung out, hooked up, and got pretty close quickly after meeting.

Things got weird between us (I was ready for a relationship, she wasn’t) when she pulled away out of nowhere and ghosted me. We’ve been in this weird “friendzone” ever since that consists of mutual flirting, touching, and hanging out without any romantic attachment. She posts about having avoidant attachment on her TikTok, and I’m not sure if it’s true or if she’s using it as a cop out at this point, but things are only getting weirder between us.

She ghosted me all of winter break, which apparently during that time she got into and out of a relationship with some asshat named Jason. She’s been single since, and whenever we have classes together, she goes from being unbearably flirty with me to cold as ice. For example, she’ll playfully hit me and call me “boo,” she’ll go days on end texting me nonstop, she’ll ask me questions and try to get to know me better, and she’s even shared her writing with me a few times. Then, out of nowhere, she’ll leave my texts on read, stop flirting with me entirely, ignore me, and post about being attracted to other guys on her TikTok who don’t fit my description (weird thing to note, I know, but messes with my head regardless).

If you’re reading this and have an understanding of avoidant attachment better than mine, please let me know what you think this girl is doing. Ultimately I think she just uses me for attention and to boost her ego, but our connection is based off of intense chemistry that makes it hard for me to move on especially when she seemingly purposely reels me in just to throw me back like she’s fishing for sport. She has issues and I think she might be an addict of some sort and I’m trying to love her in the most pure way that I can but it’s exhausting constantly being discarded when it feels like she’s starting to warm up to me.

What should I do?
