There's a guy who I dated online for two months, before he went offline for three months (the place he was staying at didn't have internet) before he went online again a couple of weeks ago. The problem is, I can't see us ending up together. It's nothing against him, it's just not realistic. I don't know how to break up with him without his feelings being hurt. I don't know what to do if he begs me to stay with him. I want to be friends with him, if possible.
