If there's anything I learned from my mother, never run back to an abuser. He may have done nice things for you during your marriage. But, staying with him will just make you miserable. My mom was with my ex stepfather for seven miserable years. She was supposed to have filed for divorce back in 2003 (but only got a limited divorce which is a separation here in MD). She never did. Stayed at his new place for about 8 months after we lost the home we all lived in and it was a disaster. The same arguing and bickering that took place at our old place started happening at his house. It was awful.
