Great with a married man...but is that it?

I've been in this same exact situation, so I can't judge you. I was completely in love with a married man and he constantly told me he was leaving his wife, that he was unhappy in his marriage, she doesn't understand him, and that he loves me and wants to be with me. I left him, and now, 5 years later he is still married to her and they're having their second child. Pay attention to his ACTIONS, not his WORDS.
