Dear Kristi,

While I was at home for Christmas break, I messed up pretty bad. At a party one night I ended up running into my ex-boyfriend and we started talking and just being friendly. A few hours and drinks later, it got too friendly. We ended up having sex in his car. The problem is, I have a boyfriend. We haven’t been together all that long but I really like him. I don’t know if I should keep it a secret and just look at it as a drunken mistake, or tell him the truth and hope for the best. I’m confused because I’d like to move on and work it out but at the same time I’m doubting our relationship because I don’t think I would have cheated if it mattered that much. What do I do?

Dear Unfaithful,

Oh, the things we do while intoxicated. I doubt that you set out with the intention of being unfaithful, but the fact is you were. Drunk or sober, you still cheated, and if the relationship was serious and meant a lot to you, you wouldn’t have. Tell your boyfriend what happened, and be understanding of whatever he decides to do with you. You’re in the wrong here, and it’s time to own up to your actions. Most people won’t take a cheater back, so be prepared for the worst. If he wants to work on things, then try a little harder the next time around. Always be truthful, even if it will hurt the people you care about. Maybe a relationship isn’t what you really want at this point.
