advice ???

vc
So my boyfriend is down in FL for spring break, I am too but I have to stay with my team about an hour 1/2 away from where he's staying. I dont think he'd do anything to mess up our relationship, but I still have trust issues from my past relationship. He's there with his brother and he's old 21+ so they're gonna be drinking and that's what kinda bothers me. He said he's coming to stay a few nights with us later on in the week. But I just want some advice on how to get rid of trust issues. I'm in love with him and don't want this to get in the way!
