you sound grounded and strong I know how much it all hurts- your decision to seek legal advice is a good one and to watch all money, credit cards and accounts I have known a few people with similar situations have happened with a friend and their H
our H become someone we do not know they will spend like crazy lie constantly and many of them become terrible fathers
have you stopped all contact with ow? continue to do what you are doing sounds more like tough love I wish I would have been firmer/ brought the affair into the open and filed instead of giving xh such a long time to explore his options with OW
good luck peace
