What more can he take from me?

This is more of a rant then anything. My husband and I are currently separated pending divorce.

A little history. We met when I was six and he nine. We were neighbors and friends for three years when his family moved away. We reconnected a few years later in high school. I was fourteen and him seventeen. Six months after we started being friends, we started dating. Three months into this relationship I got pregnant. I had our first daughter at 15 and 3 years later our second daughter. Three months after our youngest were born we got married.
Added (1). Fast forward to four years ago. We had a great life. We owned our own house, had around $10,000.00 in savings, had been married 14 years at that time. After 12 yearas with the same company my husband was laid off work. For the next six months he was depressed, working odd jobs until something better came up. We started getting behind in work. I returned to work full time after working part time for the last six years.
Added (2). I never finished high school and had remained a stay at home mother prior so I had limited experience. Things took a turn for the worse when his brother died in a car accident. My husband took it hard and started drinking. After a few months he just stopped caring. Our oldest daughter moved out four months shy of her eighteenth birthday because she couldn't handle his drinking. For the next nine months, he spent our entire savings, and we ended up four months behind in bills.
Added (3). I couldn't keep going at this rate so we made the decision to the sell the house. After paying back our balance on our mortgage and paying the realitor we came out just under $8000.00. My husband blew through that amount in a little under six months.
Added (4). We moved into a cheap 2 bedroom house in a terrible neighborhood, and I took on two jobs working 60 hours a week. Two years ago I started an emotional affair with my supervisor. Six months ago he asked me to move in with him. So my youngest daughter who is almost 17 and I moved in with him. I filed for divorce, asking for sole custody of our daughter, possession of the newer of the two cars we own, and agreed to pay 1/2 the debt we acquired. (We own a 2006 Ford Focus and a 1997 Dodge Neon.
Added (5). He petitioned (I have no idea where he got the money from for a lawyer) saying he wants half the value of both cars, spousal support of $400.00 a month for five years and for me to keep him on my health insurance for at least a year. I'm floored he even thinks he is entitled to this. I have no assets besides two car. I lost everything including a relationship with my oldest daughter whom I haven't talked to our seen in almost a year because of him.
Added (6). Am I unreasonable in what I'm asking for? He can keep everything in the house: (tv, table, furniture, bed, etc.) I'm sure he can sell it for something, and a car (which I payed for him to use, since he totalled off his).

All I want is for the newer car (which I also paid for since he sold the car he bought before). I'll take on half the debt, not asking for child support. He is on my health insurance until the end of December.
Added (7). ?: I all ready left him for another man. I'm living with him now, in his house. I don't have to work two jobs anymore. I can go back to a normal 40 hour work week. I currently have possession of the newer car, and left the other car for my husband to use. I even started paying down some of the debt. I really want him out of my life for good.
Added (8). Another Crone: There is our minor daughter which he isn't asking for any custody of because he know he wouldn't get any because: a) she doesn't want to be around him (she's almost 17) and b) he is an alcoholic
Added (9). ?: My daughter doesn't want anything to do with him. My oldest one hasn't spoken to him in four years, and my youngest has been telling me to leave her dad even before I found someone else. I know cheating was wrong but he emotionally checked out and it kind of happened. I just want to move on. My daughter can see him whenever she wants.
Added (10). IMPORTANT UPDATE: I think there is some confusion in my posts. My oldest daughter is 21 years old right now. She moved out shortly after her dad started drinking at almost 18 years old. We had an estranged relationship because I wouldn't leave her father. A year ago we stopped talking all together. The emotional affair has nothing to do with my oldest relationship. My youngest is glad that I moved in with my boss (now boyfriend). I'm also 36 years old and not 32.
