How would you split up stuff?

if you and your partner are splitting up who gets what? my bf is constantly leaving me alone with the babies, he talks so much shit to me..he doesn't want to work.. leaves everything on me. has called me a bitch made me feel worthless, and I just can't take enough I really can't. I feel worthless, I always feel like me and my kids are always his last prioties..he left 6 hours ago and probably won't come back real late or at all since he does this from time to time. I work 5 in the morning and I don't know who is going to take care of the babies. if I go to my mom's house I would have to call a. uber there 20$ then another $20 in the morning since my job is close to where I live then again back to her place I am crying none stop and I just can't I can't guys he is selfish he is costing me my job that i just started he is putting me through hell. I just want to grab EVERTHING I own and really ending it this weekend. he is always going to do this to me, he is never going to change he is going to always say it's my fault and make.me feel like it is. we barely bought things (well his mom bough us furniture) that I obviously can't take or have room even if I wanted to but I don't know if anything else I am legally able to take. we have 2 tvs. one I bought him for his birthday that he can keep the other he had before he met me (it's not a good t.v. but it's still a tv) will I be wrong to take some things? What if we bought kitchenware things, etc?
