I agree that if he talks to you about it that he's probably pretty trust worthy. It's when he hides it or lies about it that problems arise. My current bf and I talk about exes openly because we understand that we'll probably run into them from time to time and neither of us want to be thinking "I wonder if they still have feelings for them" so we talk about it.

One thing I noticed about my ex (the one I talked about preiously) that differs from my current bf is the constant concealing of anything like a cell phone etc... Like his phone would ring and if he were in the other room I'd pick it up, look at the screen and say "blah blah blah is calling" and that would make him really mad. Sometimes he would snatch his phone out of my hand or turn it away from me or wait until I was out of the room to text someone back which always got to me. My current boyfriend asks me to answer his phone and will show me texts he's gotten or sent even if I don't ask. He also doesn't hesitate to check his email if I'm there, go on his facebook or myspace or anything else. That lets me know that he doesn't have anything to hide.

Sorry...another story lol. My ex that I've been talking about made plans with some girl friends up in Chicago that he was going to be there for New Years (this was on facebook) so when I got on it does the little updates and said that he had written that to a girl. And I said "so you're going to be in Chicago on New Years? Were you going to tell me?" and he said "where did you see that?" like he didn't want me to know and when I asked if he was going to tell me he said "well I guess I just did".

Anyways lol as long as he doesn't act like the jerk I've been talking about I think you're safe. Best bet is to always be open with each other. And once again, sorry all my posts have been so long!
