K, do you have a good lawyer? Trying to intimidate you like that (I have a good lawyer...) made me mad,immediately thinking I wish there is a way you could take him to the cleaners (is that how you say it?).
Is there any chance that you are missing something? Is there any chance that you are eligible for A LOT more than what he says? Is there a chance his joing account with her is a way to protect his money from you? I dont know how things work there but I do wish you could get all you deserve. UNTIL THEN, let your L loose and ask him/her to be tough. No more playing nice. But you, stay quiet... K
