Sending you many hugs. I don't know if this marriage is over, because I see nothing in it that I class as marriage to start with. Abuse, anger, non-support, drunkeness, and now your feelings of apathy are not the building blocks for marriage.
You have another precious life to consider, your baby....and this is not the life or atmosphere you want them to come into,...heck you don't want it for you.
Maybe it is the time to start making determined plans for getting out and away from your Mr Toxic before your child is part of this nasty existence.
God bless
