From the time lines I have gotten from the information a friend got directly from this girl, I am not sure if he started talking to her while we were still together or not. I am making an assumption (I tend to assume the worst about everything).

Yes, he's not someone I need in my life. I guess I am just having a hard time moving on and forgetting about it because the whole thing doesn't make sense. And I know there were lies. Hard to get closure I suppose. I know people say you should get closure from within yourself. I'm just finding it too difficult. It's also been long enough now that I should be further along in the getting over process. I guess my depression and low self esteem are holding me back from moving on and just getting over it. Depression really sucks.
