Natasha,
This forum has addressed the go/stay question before.
It is an individual decision.
I totally respect that you are going to do what is best for the children. And in that there is still hope. Hope that this HUGE decision you are making will be the final straw that brings their Dad to his senses.
Though you have painted a pretty grim picture of a man who isn't about to pull it together.
Best to your whole family. This is very sad.
Carol
PS: Mike knows I won't stay 5 minutes if he starts drinking again!
