Most Helpful Guy
Yes, I think you're doing the right thing. If you know you won't be faithful (kudos for knowing yourself) and that it hurts him when you cheat, the kindest thing to do is let him find the right woman for himself. And, for yourself, find someone who is good with an open relationship so you don't hurt the next guy, too.

You certainly do not love HIM. You are in love with the idea of BEING in love. I hope for your sake you do not really fall for a guy and then find he cheats on you. if it happens, I think it will be payback time.
