I agree with everyone,put it away and come back to it someday. We are kinda going thru the same thing with my Grandson. He is iraq right now just found out he will be there for 1 year. Has a son 7 now his wife wants to call it quits while he is over there where he needs to be careful and not have this on him. Maybe your sons wife will see the light and not do anything stupid and they will be able to get things straight. I hope and pray this will happen. but until you find out put it away.
Thoughts and prayers are with you.
