Deciding whether to get divorced or not? We have 4 kids togther. I just dont love him anymore.

So my husband and I have been together for 4 1/2 years. Married for 2 years, we have know each other for 10 years. We have 2 kids form our marriage 3 yrs and 6 mos. I have 2 kids for previous relationship 9 and 7 years. My husbands thinks of them as his own. He has a 5 year old form his first marrage. Well a year ago I found out that my husband had cheated on my twice since we been together. I thought that I could get over it. I cant. He hasnt worked in a year. He doesnt really help around the house, unless I throw a fit. I work midnight and go to college full time. He just started college full time. He is angry all the time and sits on the computer all day playing games. He has changed so much form when I first meet him. I dont know if I love him or who he used to be? I am just sick and tired of everything. He doesnt really listen when I tell him how unhappy I am. He pretty much just thinks I should be over his cheating and move on. I think that I want to leave him but he has no job, no money and no where to go. I dont know what to do. He isnt close with his familyt at all, plus they live in a totally dofferent state. ANy advice?
