Relationship advice?

Basically, me and my boyfriend had be en fight all day. Because he wants to leave and take our son. I can't keep him alone because I have work and school and I dont have anyone else to stay with the baby. I dont want him to leave and I damn sure dont want him to take my son. I been abused all my life and he start the same violent shit. He been through a lot and I been through a lot. He been acting like he dont care all day. He say he done and dont love me anymore. We were literally good for the past few days now he says he dont love me. Which is random. I don't know what to do here. This shit is just so fucked up.
