How to leave this relationship

OK so my husband was physically abusive towards me for about 4 years but now is mentally and emotionally abusive and I just want out I've tried leaving but he finds out where I am I even tried to kick him out but refuses to leave he is only financially there for my children and is rarely home but when he is home I just want to run away like today he leaves to have a drink with a family member and I tell him I was taking the kids to the park and he gets mad that my sister and nephew wants to tag along and calls me sneaky and dumb and why he is still with me but he won't leave I even tried to talk to someone else to get him to leave me but he just brushed it off I'm just so tired I'm saving money to move out of stay but everywhere is so much more expensive than where I live now I just want to disappear and have a man that truly loves me and my kids
