1. I think a relationship seminar makes more sense than a boyfriend seminar. I know you're basing it off of a book but a general message might be better than just pinpointing the guys.
Maybe some stuff about how respecting and loving yourself better allows you to respect and love someone else. Stuff about balancing a relationship with being a college student. Communication, dating on a budget, and stuff like that.
2. Geesh...as an undergrad, what was my take on relationships? I don't remember. I know it was nothing like it is now. So I won't impose my viewpoints of relationships on a group of 18-22 yr olds.
