SAHM trying to leave

My daughter is now 13 months old and my relationship with her father has grown to be such a terrible thing. I really don’t need to get into all of the details but we are simply not meant for each other. He is a great father but a terrible partner and I’ve reached my point. I currently have nothing. Not a single dime to my name and no one to really help me. I have one family member who is able to help which is my younger sister who is still in college and I could not ever ask her for a thing. Does anyone have any suggestions of what I should do/ start doing to make it less risky for me to leave? I want to make sure my daughter and I (mostly my daughter) are safe and healthy. Please let me know
