It sounds to me that he is a cheater who got caught. I don’t doubt that the loves you but he will never be faithful. You did the right thing by leaving.. I know its hard but you will be better off in the long run.
Don’t let him try and soften you regarding the numbers. Make sure you get what you are entitled to because once he moves out and on – he won’t care about your well being. Make sure you take care of yourself and protect your financial future.
Once that is all sorted out – you will move forward to a better life!
