<human>: Give me the gist of the text in a nutshell

Well to start things off I was in a relationship with this girl for two years and never had felt more strongly about a girl as I did her. We broke up recently and go to neighboring colleges. I miss the girl to death and genuinely do want her back in my life, but I'm more concerned about the person she's becoming.

The past three weekends have been rough to say the least for her. She's been getting with multiple guys each weekend and has passed out at parties a few times. Never would I have seen this coming previously and I'm concerned for her. 

To make things worse she directly told me these things, not in a bragging way, but she told me she felt terrible about herself. That obviously hurt because I was always the person there for her to support her but now that she's gotten rid of me I can't do that for her anymore.

What the hell is going on here? Should I be losing sleep over the well being of this girl that broke my heart? I don't know the answers all I know is I can't stand the person she's been the past few weeks and I hope that isn't who she's becoming.
<bot>: Ex has turned in to someone I can't stand, but its causing me to lose sleep because I don't want to see her end up like that
