CG said: I would make an appt. to see an attny ASAP to also check out your legal options. If you really think about it, it makes no sense that he tells you that you can have it all and it all belongs to you anyway yet he still feels the need to check out his options.
I think CG is right and you should think about start gathering legal advice depending on your state's laws. Could YOU wind up paying spousal support or whatever even though he is WAH because you have the house and money? I don't know. Could he get half of your house? I don't know. Maybe in some states. Find out.
