What are my options if my husband said he was wanting a divorce 4 months ago but neither can afford to move out?

I have a part time job at a grade school but was in the process of getting a certification that would eventually get me full time pay, hours and benefits. I didn’t push for him to file. I still hoped we would work it out. He wants to go uncontested but he doesn't want to move out. I have 2 kids age 11 and 13. They are his step kids but we have been together for 10 years in September. He keeps threatening to kick me out just because I don't want to move out. I can't afford mortgage. I am so close to getting the full time job but it'll be a few months. In the meantime, he can't afford to move out. He makes good money but we are in debt. His family and friends have pets and he's highly allergic. I cry every day because of seeing him. He sleeps on the bed and I'm on the couch. He will budge once in a while on that. But the serious thing for me is he bullies me. He pushed me once in front of the kids. Only one time but they saw it and he said he barely shoved me and so on. He has said mean things to me and about me in front of the kids. He has lost his temper and screamed and threw things around. When he does those things, he says that that is why I should move out that the kids shouldn't be around that. I have nowhere to go but I can't get him to leave. He wanted the divorce. I'm starting to have panic attacks and I feel extremely guilty about the damage it is doing to my kids psyche. I try and keep it together but when everyone goes to sleep, I cry for hours. I have gone out to a friend’s house with his permission and stayed until early morning to just have someone to vent to. Now he said I will look bad. He's being a bully.
