I'm so sorry M for all that you are going through.
I have to ask the obvious however....How much longer are you planning to continue living as husband and wife? I don't see any chance of his behavior and treatment of you changing once your baby is born. Isn't this how he always treats you, with contempt?
Wishing you well. Isn't there ANYONE (family, friends) that you can call when you need help and/or need to go to a hospital? Your *husband*can not be trusted or counted on in any way, shape or form and he has proved that time and time again. He's a loose canon. I sooo hope you will come to terms with this fact very soon hun and move forward.
