Should I just divorce my alcoholic husband?

I have been married to an alcoholic for over 10 years now. He's in the military. We go months sometimes without seeing each other but we talk several times everyday. The past few years his drinking has gotten worse. He can no longer control it. He gets so drunk that he punches holes in the walls, throws things, says mean things to me and our children, who are both under 6 yrs old. and he just does'nt care if his actions hurt us anymore. He is drunk 5 or 6 days a week. The 1 or 2 days a week that he is sober are great and the old person that I fell in love with comes back but it's just getting old having to wait on that person to return when most of the time he's drunk and I'm left alone mentally and physically. I just don't know what to do anymore. I've been a stay-at-home mom since my kids were born and I'm nervous about how much everything would change if I divorced him. My children have everything they could ever ask for right now and when he's away for months our home is peaceful. This is a very lonely marriage though and I feel stuck. He refuses to seek help.
