Losing custody rights to D7 would kill me. I will definately consult a lawyer before making any physical move.
I also believe that children need both parents. Unfortunately my W does not think that is very important right now. She has other priorities.
Quite honestly, I think that me and my family (parents, sister etc.) have much better values than my wife and her .........well let'S just keep it at her familly or people will say that I am angry.
One day if someone thinks it is pertinennt for me to describe in one sentence each member of my wife's family....you will not believe it. Come to think of it, perhaps it would shed a little light on who she is. I always held on to the belief that my W was different. Although I love her still, I have to admit that she did not get too much help developing values.
