How do you leave this?

how do you leave an abusive relationship when you're scared to leave and you still love him and wish things would work. I'm sitting here with my newborn just crying and trying to get the strength to pack and go

edit.. thank you for the support.. I just put the baby to bed .. he said he doesn't care about or love the baby and hes disowning her and me.. I am hurting so bad for me and my daughter
