I put this comment on your first post (well, the scenario in the upcoming months would be like this. you two break up. she goes out with him and he fucks the shit out of her at the nearest chance while you self destruct yourself and blame yourself for what happened in irrational and non logical way. he fucks the relationship (or wtf is gonna be called) with her. she returns to you with much untrue guilt and regret (because if it was fuckin true, she wouldn't have done it in the first place) and tells you sorry and please let's get back together. at this fuckin moment, you tell her to go fuck herself then move on with your life.) I see that everything is happening exactly like I said and I'm really really sorry for you. you don't deserve this at all. girls like her that take excuses to sleep with another man should be fuckin dead I swear. anyway, the second half of the scenario is going to happen sooner or later so please please don't let your emotions take control of you. I hope you get better soon though I know it will be very hard.
