How do you chose between the one you......?

-I am in need of some advice.. girl or guys, it doesn't matter.. Sorry if it gets long.

Okay so i have been on and off with a guy for the past 5 years. We have a child, almost a year old, together. Me and my bf do not get a long.. at all. we havent since a few months after we got together. we argue over everything. he has cheated on me and left me for other girls multiple times.. but i always forgive him and beg for him back.. idk why, but i do. I try to just look at the good things, not all the bad. Well anyways, he treats me like shi+.If i try to tell him my feelings, he straight up tells me that he doesnt care and to stop crying. He calls me names, I call him names.. its just not healthy. We are always trying to leave each other but once he tries to leave I want him to stay. we fight every day. not big fights, but there is at least one argument daily. Idk what to do anymore. I work to pay for all the bills, and everything we need for our apartment and son. My bf does not have ajob, and does not clean the house. I am so stressed out all the time. He tells me I am crazy every day.. can someone please help! do we stay together for the kid or break up!!He isn't helping your kid at all, I know that's why you want to stay with him but leave while your baby can't remember. He doesn't deserve hearing all the fighting and the stress and neither do you! I know it's really hard but you need to leave him and get a restraining order or something if you need to it sounds like he would get really upset but leave before it gets worse. My mom stayed with my abusive dad for 20 years for me and my brother but he started hitting us so she finally left him because she realized it was hurting us too.
