I used too get upset when I thought about my ex with someone else, being happy when Iwas the one who was there through all the ****.......after a good rant and rave I pull my self together and know that even if he wanted me back I could never look at him the same way, to much pain. I have a hard time trusting, how can we not we were hurt so bad. However I try not to judge others by his mistakes or mine, I keep a open mind. It gets easier over time, but I think what helps me the most is just letting go.
