<human>: Can you provide a brief overview of the text?

Title is pretty self explanatory. The details of her cheating on me aren't really important, but it hit me pretty hard. She was the first girl I actually loved, and I'm still dealing with the anger, sadness and self esteem issues that come with something like this.

The other day, she started sending me pictures of her hanging out with my best friend. I was a little hurt at first that my best friend was spending time with this girl who had torn my heart out, especially since they weren't "friends" before we broke up.

I spoke to him about it, and he told me while she was flirting with him and trying to hook up with him, he would never reciprocate. I don't know if I'm taking this too hard, but I'm a real mess right now.

I've always had bouts of depression, but nothing like this. I don't want to have to feel like this day after day. I'm hurt that my best friend didn't talk to me about what was going on until I brought it up. I'm hurt that he continues to hang out with her even though he knows her intentions. Most of all, it's driving me crazy that this girl I loved/still love doesn't want anything to do with me but thinks my best friend is worth hooking up with.
<bot>: S/O of half a year cheated on me, I still love her and now she's trying to hook up with my best friend.
