trouble with exes

ok heres the deal my guy and I have been together for two and a half years. Well a couple of months ago I started to talk to my ex on the phone not about anything special just as friends I have been very open about it with my current boyfriend and have told him everything we don't keep secrets and beleive that it's ok to be friends with your ex. Well tonight he went to a hockey game with some old friends back from high school and one of them is his ex's twin brother who we hang out with all the time anyways. I had to work and he's always complaining that I don't give him enough time to hang out with his friends so I thought it would be a great oppurtunity for him to have a guys night out. Well it just so happened that his ex ended up going along. I got really upset and angry with him and now he's being a total jerk about it I mean I am hurt cuz I speciffically asked hin if she was going and he said no considering she lives out of state. I don't blame him for going I didn't expect him to turn around and come home he was there and didn't know she was going and they were with like 7 people, but I can't help but feel jealous I don't hang out with my ex and I know it's stupid cuz he told me she was there and what they talked about and all I feel I have no right to be mad at him considering they were friends after they broke up and he came home to me but I still flipped out and now he's being a big jerk about it telling me he doesn't think it's wrong for him to hang out with her just as it's not wrong for me to be friends with my ex or hang out as long as it's with a group of people then why do I feel so jealous and hurt still and betrayed what should I do?

Well I can see why you are jealous, but remember your b/f may not have all the answers for you....so that may be why he seems like a "jerk"about it. You have to keep the jealousy feeling from getting the best of you, and give him your trust. In givin time your trust for him WILL be appreciated. Give yourself some credit also, yall are together and have been open about the relationship. Which is a good place to be. ;)

It can be only for one reason. You don't trust him (maybe because you are not sure he loves you).

Do you have a reason not to trust him?
