I've asked my husband to move out and he will not go. What would you do?

Here's the back story.  He's a bum.  He hasn't held a job since 2005 when he was discharged from active duty.  He is bipolar and is an alcoholic, both of which have escalated to the point where I am completely and totally done.  I do not wish to live with him any longer.  He has done nothing but making promises of quitting drinking, getting jobs, and being a better husband and father and never makes good.  In the past year or so, he has also started looking at internet porn which is disgusting, but whatever, if that's what he wants to do, fine, do it on his own computer in his own house.  NOT MINE!  He has repeatedly done it on my computer and has given me viruses on at least three occasions which nearly put me out of work for a week.  So now I have to treat him like one of the kids and make sure my computers are either off or locked whenever I leave the house.  No one can know my passwords.  He gets drunk daily and passes out on the couch.  He has repeatedly promised to do the housework, laundry, etc which he never does.  He simply sits on the couch and watches television day in and day out.  So here I am working 2! jobs to make ends meet, doing laundry, cleaning the house, running the kids here and there, and he is asleep on the couch every single day.  I really feel as though I hate him!  He has basically destroyed his body.  He's got a beer belly, his face is puffy with tons of wrinkles and bags under his eyes and he is only 45!  And all his drinking in addition to his mental illness has pickled his brain.  He cannot remember anything.  I will tell him the same thing four differen times and he still doesn't remember.  He cannot carry on an intelligent, coherent conversation.  He is completely useless.

At one point, at the urging of a doctor at the VA Center, he decided to apply for disability because of his mental illness.  He kept telling me I needed to help him fill out the application.  So okay, I get online and find out what paperwork he will need in order to fill out the application.  I gave him a list of what he needed which basically consisted of all of his DD-214 papers which are his discharge papers from all active duty tours, he needed all his medical records documenting when he was diagnosed with mental illness, treatments he had, doctors he seen, etc.  All of which he would have to obtain from the VA.  He said he was going to spend a day at the VA Hospital filling out the right paperwork and retrieving the documents.  He never did even go.  Then when we get into a fight, he says it's my fault he hasn't applied for disability because I wouldn't help him!

So now I have basically told him I cannot do this anymore.  I do not want to be married to him, that I resent him, and I can't stand the sight of him, and I want him to move out.  He has a buddy that he has moved in with before who will gladly take him back, so it's not as though he has no place to go.  He simply will not leave and I am stumped as to what to do.  He doesn't beat me or the kids.  He's not a "danger" so to speak.  I am going to file for divorce next week, but I would like to not have to live with him through the entire process.  So what would you all do?  I've thought about just renting an apartment and moving me and the kids out.  My son is 19 and he has friends he generally stays with off and on anyway.  So it would really just be me and my 11 yo daughter.  There's a 2BR apartment for rent just down the road from my house, but if I leave my house, will I lose my rights to it?  Will he get it in the divorce?  It's not worth much.  It's a 60 year old 2 BR that needs work.  We bought it for $40,000 and paid it off, but we still owe two years worth of property taxes on it.  So really I'm not losing a whole lot, but it's just the principle of it.  He is a complete deadbeat bum, and he gets a paid for house to live in!

Right now I'm just so angry with him.  He basically just got through begging me to give him a chance to be a better husband and he said he was going to clean the kitchen, the bathroom, and finish the laundry to which I laughed and said you've been promising that for years.  He said he was going to prove me wrong.  Guess where he is right now?  Passed out on the couch.  I'm so done.  Any suggestions?
