I agree he's got an addiction and other issues that need to be treated but he has completely stopped therapy. I also need to protect myself financially. While in this affair fog or whatever it is he has blown a significant amount of Money and accumulated debt traveling the country with OW. He used to be very smart with money. I'm not so confident now.
I hope you're documenting all of that. Any family court judge worth his/her salt isn't going to look too kindly to his squandering joint marital assets on his infidelity. At a MINIMUM, such funds should come out of HIS side of any financial settlement from the D.
