How do you get over someone?

How do you get over someone you’ve been with for four years? How? I never ever ever ever wanted to be a single mom, let alone at 19 years old.

We have a beautiful daughter he doesn’t look after, we live in an apartment I pay for, he doesn’t work, doesn’t do shit around the house, hates my mom, grandmother and constantly says horrible things about them.

I’ve had enough, told him to leave, and part of me feels good, but I’m also so torn I can’t even explain it. He’s an ass and I know it, he stays in bed till 5pm, I work fulltime, after work I have to go to the store for food because he doesnt, I have to do everything for our daughter, I don’t mind because I love her, but it’s just way too much too handle all by myself, especially when he’s home all day doing nothing, and not even cleaning up his own mess.

Can yall give me some tips on how to get over him please, or what to do 💔
