Should i give this guy a chance!?

ok... i'm a guy. But if I was like that, i dont think I would deserve anyone. Junior year, drunk driving.... I don't think he is a very positive influence. If you are 3 years apart, I don't think that's the best age diff. for a relationship. I would just tell him that you aren't looking for someone right now. At least stay pure for your future husband. Everyone that I have talked to said to stay a virgin until you're married because they regret having without being married.
