I'm just gonna be brutually honest here. When are you going to man up and move back in? You are losing time with your kids and if this divorce does go thru you've already established that she is the major care giver. It is 50% your house and those kids are 50% yours too. You've tried it her way and that isnt helping you at all. Move back in immediately. Your wife will tell you that she needs space and all that stinkin garbage. Tell her you will help in any way you can, you have given her space and your relationship with your children is suffering. If she is adament about needing space then you are more than willing to help her pack.
