Donna, I'm so sorry. Seems like many people disappoint you lately, and that is so sad, and hurtful (experienced betrayal myself several times in my life, and some of these wounds never fully heal, as it seems).

Well, you can only make guesses why he did not tell you about his marriage. Makes you wonder...
Maybe you should confront him, and ask him to explain why he was dishonest to you! Was he the one who has told you to get rid of your cats?
