i know a few women out there that would say Well you too must have been splitting up, but we weren't and i'm just wanting some other women to give me some incite.

As to any other possibilities that could have contributed to her decision,
she did a guy at a party when i had been away for 2 months (on research trip) she hooked up with some Old friend that had hounded her before, but she said that had nothing to do with it but i don't believe her, should i? its been 5 month's since the split she and i have remained single but have seen each other at friends party's her friends want me to get back with her and my friends don't care about her at all. My best mate helped me after the split
(and considering he stayed awake until his exam the following morning talking to me) he said to me the other day "When are you going to move on? its been ages since you've even Gone to a party with us?" But you know shit happens and i'm just wanting closure just wondering if anyone can give me incite into WHY?
