Just wanted to say hello, and to let you know that you ar not alone. I have a very similar situation to yours except that we don't have any children.
I can fully relate to your feeling like a zombie, just bearly surviving, and that's when I came here. Everyone one here feels similar feelings, because we have all been through it.
In my case it is the angry, annoying feelings that give me the strength to be my own person. You can't make him stop drinking. It is a hard thing and I can fully relate to the no appologies....I 've never got any either.
but i have learned that we put expectations on them and when they fail to live up to them we get upset and hurt... so we learn not to expect anything, except from ourselves.
Be strong.....Know that you have all the support in the world here!!!
Sending you a big hug
Steph
