What was the most fucked up thing your ex did after you broke up?

Been a lurker for a long time, but I actually have a story for this one.

My ex (of a bit over a year) was a very clingy type one that would hardly ever leave me alone. I consistently asked her to give me more space for months, but she would maybe give me a day alone then go back to her same ways. Finally, I broke up with her and shit went bad. First of all, I messed up by leaking it to one of our mutual best friends, who told her I was going to break up with her before I was actually able to go do the deed. My girlfriend was a former cutter, something that I wouldn't allow while I was with her. Before I could go break up with her, she cut herself really deep on the leg, and had to go to the emergency room to get stitched up. It made me really sad knowing that someone I cared about was hurting themselves because of me. But that was just the cherry on top of the fucked up sundae.

Within the day or two after I broke up with her, she thought it would be a great idea to call her previous boyfriend, who she was with for two years before she was with me. She knew this guy was abusive at times, he even had to be put into a therapy program because he was so depressed, his entire family was certain that he was going to kill himself over this girl. She knew he was dangerous, and had previously said that she would never talk to him again because of the things he had said and done since their break up. But she thought it would be a great idea to call him from a state away and have him come up to visit.

Next thing I know, I'm over at her house consoling her because she got raped by this prick. So there's a lot of tears and whatnot, you know the story, but we're drinking some beers throughout the night and this goes on for quite a while. So when I'm finally about to leave she starts trying to get me to have sex with her. Immediate red flag. WTF? shouldn't she be afraid of having sex for a while? Idk, atleast that's how the movies and shit I've seen go. But, drunk and stupid me thinks to himself, "I can't let her think she's damaged goods, or that I think less of her because of what has happened." So we did it.

That kind of fucked me up in the head for a few days. It was really confusing for multiple reasons. A few days later, we're at the bar having some drinks. She asks me for a cigarette, I say sorry no, I only have 2 left. She gets mad and leaves. We're all going back over to their (her/her roommates, and one of their neighbors) places. As we open the door (which is obviously "conveniently" placed right in front of the door) there she is under a blanket just blowing a random dude.

You know what she said when I spoke to her on the phone, amidst all of the "you're my best friend and I would be devastated to lose you" crap? This is what she said, and I'll never forget it, "Sorry, I'm not sorry."

TL;DR: That day I was the one who was Rekt
