My boyfriend and I have been dating for almost 14 months now. He is in college, but I am in high school still. We have both been very faithful in our relationship, and he has given me no reason not to trust him, but he planned a vacation with three of his friends, two of whom are girls. He and one of the girls are driving to New Orleans, where the other two live, and they're spending a few days there. I know that I trust him, but this just makes me nervous. I love him and I don't want to mess things up by worrying too much. I can't go on the trip because I am in school that week. What can I do?
