No, that is not possible. Logically speaking NO. I mean if you are dating someone else while you love someone means it's clear you actually don't love that person otherwise you wouldn't even think of dating someone else.

I'm curious to see what every one has yet to say. I think the answer is yes, because I have been there. Except I don't know if I will call it "happy". I guess I was just satisfied while dating that someone else. I knew in the back of my mind that I still missed and loved my ex, and I actually was dating someone else to get my mind off of him. Did you break up with him? Or other way around?
I think he may have feelings for you. To be honest with you, sometimes they linger. He may be trying to be playing games with you as well. Either way, its affecting you so I say you either confront him or cut things off. You'll never know what he's really thinking until you ask. I just wouldn't risk to assume.
