I am having an affair with a man I met online two years ago - i'm married and he is divorced/single. It's mostly physical even though when I asked him about it he says its more, but I know for a fact he dates other people/participates in other affairs. He cancels plans on me at a moment's notice and is generally standoffish...but the sex is amazing. I'm not sure what to do - I feel like I don't have a right to ask for more but I am feeling pretty worthless. What should I do?
