My (bisexual) boyfriend and I have been dating for almost two years now. I love him very much and he really loves me and I trust him a lot. He wants to go on a week-long trip out of the state with his friends: two guys and a girl, and they'll be staying in a hotel room together. I haven't met any of these friends but I've heard about them. My boyfriend is excited for his first adventure without his parents around and I feel awful for my reluctance but I also feel skeptical. He's always been honest with me and I'm probably overreacting or being too emotional, but should I agree to let him go on this trip? Side note: We're kind of long distance and so we barely see each other more than once a week, so I don't feel we need "a break" or anything.
