Too pregnant for this crap ☹️

So as of rn I’m 38 weeks & 1 day pregnant, and to make a long story short. My child’s father had been cheating on me and all that stuff. So we break up and I was like we can co parent and I’ll keep you updated w everything. Saying you can always come see him and when I go into labor etc. So he gets mad and goes on a rant and literally said he will be a dead beat to our child. I just don’t understand how you can mentally and emotionally abused the mother of your child while she’s carrying your child then tops it off by saying you’re going to abandon YOUR child.
