My fiancé is going to be going to Florida (we live in Ca) for one of his good friends weddings. Chances are, I won’t be able to go (nursing school that I can’t miss) and I have a really hard time trusting him in situations where I know he’ll be drinking (he drinks excessively and doesn’t really talk to me). There have been past issues that I’m trying to work through. I want to trust him so badly, but it’s really hard for me in these circumstances (he’ll prob go to the bachelor party, and this friend really eggs him on to drink and do stupid things). I guess I’m asking how to trust someone that’s broken your trust in the past. 
I want to trust him and not be jealous / crazy, but it’s really hard with the past. Not really looking for the “leave him” response. More someone whose been in this situation and overcome it. He’s the only help I have with my son to work and finish nursing school. I obviously love him, but the trust thing is eating at me.
