I know how you feel. I'm in a similar situation as far as the verbal abuse goes, but I'm better off in that we're not married and there are no kids to consider. A reasonable-thinking person would walk out the door and never look back, but when love is involved, it's not a simple solution.

It's clear you still love him and want him to get help. He MUST get help. There is no alternative. You make the call. Get a recommendation on a good psychiatrist TODAY (or tomorrow since it's Sunday), make the call and tell them of the urgency of the situation and make the appointment. Tell him you will take him to the appointment. If he refuses to go tell him you have no other choice but to take your kids and find other quarters. There are shelters that house women and children of abusive spouses. While he hasn't physically hurt you YET and you believe he never would, the threat is still there when emotions get out of control. There are countless incidents where spouses are killed in the heat of an argument and the person doing the killing didn't "mean to" do it.

Be firm about it. Be firm and loving. Tell him you love him and want to stay with him, but you won't unless he gets help...and not just "someday" but RIGHT NOW.
