Actually GIMA, your wife is being quite wise in letting her lawyer handle things for her. You would be wise to let YOUR lawyer handle things for you. Is there anything stopping YOU from making an offer first?
You would be wise to stop trying to force her and pressure her (pressure does NOT work) into making decisions without her lawyer. You would be wise to drop the issue and tell your lawyer to take control here and do what he has to do. If you do that, when things don't go her way, you can use the same excuse she is using.. which is "I will have to talk to my lawyer."
