I'm not arguing the guy is a saint. He did file for a divorce according to the original post. I don't see where he is a consistent liar, but agree that he made empty promises. Even dirt bags have hearts though. I didn't say OP stabbed him in the heart with much sympathy for him, but more of a action-reaction kind of thing. If you promise to marry someone but then back out, it doesn't matter if they are the scummiest dude on the planet. They will feel betrayed. A better guy would have been more amicable about it. 

If it sounds like I'm being blunt to OP, it is because she made her bed and is surprised what she's laying in. I didn't say she is a bad person, but that she needs to learn more about herself and gain understanding for other people. She knew early on he was married and mean. She agreed to marry him regardless. She should not be surprised that a man who was scummy while she was with him will be scummy when she dumps him. Yes any sane person would've left...probably a lot earlier than OP. 

Maybe I could have summed this up easier by simply telling OP, "Don't date scumbags."
