Can someone help me, think my boyfriends manipulating me how do I handle this?

my partner/ child’s dad all week has been out all night drinking and smoking with his friends. He has not told me he’s not coming back. Everytime I set a boundary he twists it on me and says ‘ok I will move out then you’re so dramatic I don’t want to be with u anymore’ then I end up crying scared to lose him and beg for forgiveness. How do I stop doing this? What do I say when he says this to me?
