So me and my partner are not getting along

Havent the last few months of my pregnancy.

Hes older (34) then me and has kids already but thia will be my first (22).

Idk anyone thinking they might up end leaving after birth and healing?

Or is that normal to hate him this much?

I love him but hes been so mean to me at the end of all of this and maybe its my hormones but im not the kinda women that will stay after getting mistreated. Hes just so mean to me and I just feel like hes been treating me badly because he knows i need his help right now. Which is so wrong. And im scared to be a single mom. Both my parents passed when i was young and i feel like i went down a terrible path without them. I just wanted to build a family but refuse to teach my baby his morals when it comes to how women should be treated.

Is it normal to feel this way ?? Ive also tried expressing how i feel and he makes excuses up for his behavior. That he was tired or that he loves me and that Im not going anywhere.

So anyone else having the same thoughts? Are any of your partners treating you differently since your in need of there help financially?
