I've been out with this guy for a couple times, but I'm not just feeling it. The problem is, he thinks we're on the road to being Facebook official. He's a nice guy, but I don't know how to let him down gently.
It's Not Me, It's You
Dear It's Not Me,
You could do that whole not-responding-to-texts thing, but as a collegiette™, I'm thinking you probably want to be a bit more mature than that. I would advise you to be honest, but be mindful of how you tell him. There's no reason for him to have his feelings hurt if you don't feel a connection or any chemistry, but make sure you're firm and clear that your romantic relationship is over. If you really don't have the courage to do that, well, maybe this is a time to pull out the "Busy Collegiette™" card.
Hope that helps!
