Confused about what to do...

So I got married at a young age I've been with my husband for 2 years. I do love him but I think I'm starting to fall out of love with him. All he does is play video games. I work full time and I'm going back to nursing school this summer ( I took a year off). It just seems like he doesn't want to work. The whole time we've been together he hasn't held a job more than a few months. He got a really good paying job recently and only went in one day before quitting. It's the same story every time. He says he's going to work and wants me to focus on school but won't keep a job. Then a few weeks ago he told me he wanted to talk bc he felt bad. He told me four years ago he slept with another girl 4 days before he asked me out. I know is hold drop it bc it was so long ago and we weren't technically dating but it hurts. And he  said he went to a rave with his friends last year. I've asked him about the rave multiple times bc I've heard his friends say things about it and he denied it. And lately he's been snapping about the smallest things. And he never wants to let me sit still. If I have the day off he wants to be out all the time doing things. Sometimes I need to relax, not to mention I don't have the time/money to do that. I've been considering divorce. I'm not happy but I still kind of love him...he's also the only serious relationship I've had. We've gotten into fights before and he's said he's going to sleep with other women and I have to be loyal. But then took it back. I feel like it's a toxic relationship but it feels ok sometimes. I'm scared about divorce but I think it might be best. I also don't want to throw him to the street. He doesn't have a job and can't support himself.
