I say to just put your profile back up and start dating other guys. You don't owe this guy an explanation, and he'll get the message when he sees your profile back up. If he does contact you again, just say "Hey, thanks for calling, but I'm really not interested. I'm looking for a relationship and think we're just in different places." He'll probably try to convince you that he too is looking for something real but just politely say that you're no longer interested and move on. Just try to learn from this mistake and do things differently with the next guy. Believe me, the guy who is right for you will not push you to move too quickly and, when it does happen, he'll be asking you to take your profile down!
