Husband won't get a job...?

When we first got married I stayed home and my husband worked. We had four small children and then things started to get rocky. The economy failed and his income dwindled (he's self employed). I went back to work after having our first child and made up the difference. As time has gone he's worked less and less and I've worked more and more. He started up another business because he didn't want to stay home with the kids and now we pay huge money in child related expenses a month. He makes no money. Literally. He barely pays his company's bills so there's no money for us... he basically works for free, hanging out with his friends (they work with him in similar businesses). Here's what is driving me crazy. It looks like I might lose my job. I've told him that he needs to go out and get a job. He needs to make calls, put out resumes, anything. He refuses. At first he says he's going to, but then when I asked if he's called anybody he starts moping and then talks about how hard it is for him that he doesn't make as much money as I do. When I tell him that doesn't matter, he has to make SOMETHING in case I lose my job, he just talks about how depressed he is. Meanwhile, he continues to go to his job where he hangs out with his friends and makes NO money and I'm frantically working 60 hours a week to try and put some money away. He gets offended when I suggest that he apply for jobs that he thinks are beneath him, but I don't suggest any jobs that I wouldn't do myself if I lost my current job. I'm frustrated and I want out. Any suggestions?
