Unfortunaly, I don't have a solution to your problem. The reason is I'm in the same situation. The only differences are that I'm 37 and he is 57. His children are grown and I have a teenager. I ask myself the same question. We've discussed breaking up before and all the reasons why it's wrong, but he says he loves me and has never had a relationship like this before. He makes me feel very special and spends a great deal of time with me even though he is married. When you find the answer, please share.
