alcohol help

Maria
I have 7 month daughter. I live with her father. We don't love each other any more.he said that help me because I want a baby. Just live look like neighbors.But he takes alcohol every night. I tried to speak. He don't understand.
Should I stay or leave ? I wish best for my daughter I want to find real love. I am not a freak.
 What should I do?  Unfortunately I lost my parents. I have only my daughter. I love her so much.
Please some advice for me.
Thanks
