Hello I just wanted to say hi! hang in there. Having kids didn't help us in any way as time progressed so has his drinking. As the new stresses of family life came on so did the drinking. That doesn't mean it will happen in your marriage.
But I do know that it isn't your fault and know that you can't fix it or change it either by comfronting him or nagging him. I had to learn that the hard way as I am sure most people do. I know it is difficult and may get worse before it gets better as I am going through some of the worse hanging on the hope for the better that is to come. I don't have much more advice, sorry about that.
I do encourage you to hang in there and I'll be praying for you as I have started praying for all of the people I am meeting here!
