Story/Advice Time!!!

So me and my unborn child (still pregnant) father have been really going at it, when me and him fight he says a lot of messed up things like “don’t talk to ever again” “idc about u” all types of things .... but then when we have good days we are super good but this whole time has been a big game and he has done nothing but use me .... he has been at his other child’s mother house since Friday and then stayed with me last night and we slept together 🤦🏾‍♀️ we went to get him a car this morning and he has barley talked to me since and when I tell him how I feel he tells me “ I’m trippin and that I’m just pregnant” idk what to do anymore I’m just really depressed and confused.
