I agree with what everyone is saying. You need to see a lawyer ASAP and get some legal protections in place. I am in a similar situation with my alcoholic wife. I too came home to find her passed out with our 1 y/o and 3 y/o unsupervised. In my case, I filed for divorce and in less then a week I was granted emergency temporary custody of my kids until a hearing is held. It does not matter that you are male, it's what is in the best interest of your child and your unborn child. Please get help now.
