Toxic or not.

I have been with my significant other for four years now. We have a son together and he has two girls. His girls will be moving out of state at the end of the month with their mother and it’s extremely hard for everyone. My significant other would like to move to California which will be a couple hours closer than Indiana. He wants to move and I’m stuck here. I’m so close to my family. The thing is a have to do 98% of stuff with our son. I figure out baby sitters when she is out. I am the one who changes all the diapers and I do bed time and I pretty much do everything. When it comes to taking care of our son and it’s like trying to pull teeth to do anything for him and if I were to move with him it would not only be hard for me. But also our son. He’s from there so the only person/people starting over would be me and our 1year old son. I can say that he gives me the silent treatment a lot and In the past before I was pregnant he had shoved me around. He’s constantly lying and I don’t want to think all this will change once I would get down there. I am at a complete loss on what to do. Sometimes I don’t even think I should be confused. Please help me.
