<human>: we broke up because a other guy was texting her about having a three some and she was entertaining it and said she was down to do that. i did everything for this girl and did my best to keep her happy. took her out everywhere. When we broke up she even said she messed up the best relationship she ever have.

*part 2 But now she ignores me. i hear she be popping pills and i always see her hanging out with this drug dealer that is one of my old friends and she always driving him around as well.

Condense the text into a few key points
<bot>: I just want to know why she is doing that and how can you get an ex girlfriend back because i didnt do nothing wrong too her ?  .
