Toxic marriage and wanting a new start for me and my babies

Hi, my name is Kaylee. My husband is mentally abusive and is withholding money from me when we have kids together. He is always threatening to not pay our bills and belittling me. I want to get my own trade and make my own income but I've had 4 kids at the house for summer vacation so I haven't been able to work. I want to get out and divorce him so me and my babies can have a new start. Anything is appreciated. God bless.
