I spun this girl after meeting her at a party last year. She was drunk and put out on the first night. Was a complete freak in bed (even the first night) and had me fuck her outside on my deck.

Background: I'm fit and a senior at my college (22 y/o), I'd generously give myself an HB8... have access to a lot of girls. Could move on within a few weeks of being bummed of breakup. She is 20, is a hot and sexual HB7 with fat tits AKA gets hit on at every party. Can more than easily find a cock.

She got my number and would call me after nights she went out with her friends(all sluts) to end up in my bed. However I later found out, it was only when she didn't black out and pass out on another guys cock that she would end up with me. She consistently got more and more attached to me and would hit me up more and slut around less. But I didn't care at the time cause I was spinning several plates.

Anyways, 8 months later, we were consistently hooking up and I asked her out. While in the beginning of our relationship I remember finding out that she had had 25 partners (initially she said 10) with only 2 LTRs that were in high school. I also found out she once fucked 4 guys in a week(including me). Also, pretty deep in our relationship, but before we dated, she hooked up with a guy who she didn't know's name(made out with him and didn't fuck because threw up on him) after going on a date with me in the same night. [I assume this means I was BB that night, but I am alpha to her] The one thing that is consistent in her whole promiscuous past is Alcohol. Every time she went out she would drink to the point of not remembering anything(result of college culture), and I've seen her like this and it is insane. I'd call it a bipolar binge drinking disorder.

Since I asked her out, she has been loyal, and fucks me like crazy. She has several unicorn checklist qualities, but completely airballs on the N-count and drinking issues. I recently came to the understanding(thanks to red pill) that she is extremely likely to cheat. So, I broke up with her. She came back to me saying she was so sorry for her past, and that she didn't deserve this because she had been completely loyal since we officially started our relationship. She, classically, explained that she has changed. I couldn't argue with her loyalty since the relationship, as she had already stopped to only drinking with me and not going to other parties. She also promised to stop binge drinking, and to not go to any parties without me(actually really fucking difficult in the college scene). I believe this is true, but I know that if she drinks she will cheat on me.

Regardless, can I trust her to change her ways and be the unicorn that is her sober self? Or will she eventually get drunk and fuck me over behind my back. I plan on distancing myself to watch and see if she can truly avoid partying. Then de-escalate and plate her if she fucks up.

Is it possible for a girl to only be a slut when binge drinking and truly be different while sober. Or is it just a hollow excuse for being a true slut.

tl;dr: My LTR is extremely promiscuous while drunk but has loyal unicorn qualities when sober. She has promised to stop partying completely(even though her friends are in the HEAT of it). Is it possible for this to be true?
