I was established and with the majority of my family near and moved out of state to get married and have kids. Can I divorce and move back?

I had a solid career and family life and moved to marry. We've been married 4 years and have a 1 and 3 year old. I have no support system here to help me and have been a stay at home mom for the whole time. I will have to move out with my kids and I want to move back home. Husbands family all live in same town and do not have a relationship with us at all. My husband drinks 7 days a week and I no longer can keep my kids around our unhealthy marriage. What can I do to be allowed to move back home? It's about 1,200 miles. Thank you for your time.
