Seeing a girl over summer, quite serious, to the point of her asking when I get back to the city uni is in will we be a couple.

Long story short, get really wasted one night, "mean" to her on the phone, think I said something like will she just hang up so I can get with "another slut"(I know, I've been cutting getting super drunk or high out when interacting with girls because I'm a loose cannon) and sleep with another girl that night (which she doesn't know about). Im aware that I'm very much in the wrong here.

She goes NC for few weeks, then occasional texts exchanged but nothing builds (i beta'd out and paragraphed her one night about how regretful I was, she'd send me a link to a song I like but then NC my request to meet up for example).

I bump into her at uni, bit of small talk leads to me asking why she didn't respond to my last text (request to meet up when exams are done), and she says why would I even want to talk to you, how upset she was, she trusted me etc, to the point of her looking like she was about to cry in the library. Hug then I say meet up soon, she seems positive to that, says we can start off as friends which I shoot down quickly (I don't see how this is possible when you've woken up to someone's nudes for 3 months).

Anyway message her the next week asking how her holiday was and she just ignores it. Fair enough, tough one to swallow, I did like this girl but am aware my actions shot me in the foot, was extremely uncharacteristic to say those things but i was very high and have cut down on MDMA nights since then, have my phone off when out as well now, lesson learned.

Fast forward month later, she accepts my fb friend request. I made a new one around the time we'd fallen out and she just accepted it out the blue. Few days active with her and she's been tagged and tagging in posts about stupid girl shit like texting, dogs etc with this medical student who she'd complained to me a few times was getting on her nerves from him keeping trying to talk to her. I know they got with each other before I met her.

Is she just looking for more attention now this guy might be wearing on her?

Why do I ask - unfortunately in same department at uni, see her decent amount, in a group chat which is used a lot for nights out from a class last year, where she is the only one who left the class but continues to read everything, view all my snapchats etc. And with the 'gftow' advise I've banged 5 but did genuinely like this girl, had some great times, and still feel bad about how I acted to her, can't emphasise enough how high I was.. and hate fucking seeing her about! Not a big campus. I know I come off as a cunt here but that outburst was genuinely out of character and I fear the regret is eating me up a bit.

Reach out again or block her on everything
