Alright, this is the rundown on my situation.

My ex and I dated for close to 2 years. This entire time i was very redpill, I treated her like a plate, however my mistake was basically telling her I was her boyfriend and then not acting accordingly. I treated her too much like a plate, and simply didn't care enough. She's 2 years older than me (26) and I can see her approaching the wall fast, she would constantly complain about my behavior and the way i was treating her, how i wasn't behaving like "her friend's boyfriends" but i just kept telling her to stop whinging/it was fine. Anyway she ended things, telling me to go fuck myself, that i was an asshole, that she'd "wasted" 2 years of her life with me etc. I should point out i never treated her poorly. We were very, very close and absurdly similar, we had excellent times together and great sex, she just wanted the standard "boyfriend" experience and I wasn't prepared to give it to her.

So we end things, I tell her that i never meant to hurt her and that I care deeply for her etc. and wish her the best. 5 months later she messages me, we meet up and instantly start sleeping together again, I plate her as i'm involved with another woman currently. We see eachother once a week because she's a med student with limited time. When we hang out I can sense her guard is up and she's not exactly particularly "happy", she just seems like she is aware that i am "using" her (her thoughts) and that i'm not going to give her what she wants (asking her to be exclusive).

Anyway, I now haven't heard from her in nearly a month. Radio silence. She's gone from frequently chatting to me on fb, sending me links, flirting etc to nothing. Our last contact was me asking to see her and her saying she can't because of exams, but she'll be free in "3 weeks". I know exams are over and I'm yet to hear anything from her except some drunk messages telling me she "doesn't even like me".

Should I leave it alone and just wait for her to get in contact, and have faith that she will? Or should I hit her up again? I feel like hitting her up is weak given the last contact we had was me asking to see her. I don't want to lose her if i'm honest because i really do enjoy her company, like her quite a lot and would consider LTRing her because she's the closest thing to a unicorn i've ever met. I still need to play the game however.

Any advice is greatly appreciated. Thanks guys.
