I was wondering how do you transition into being a single mom?

My bf ended up cheating on me. I never thought I would say that because he was always afraid that I would. He’s the only person I’ve ever been with I can’t imagine being intimate with anyone else. I keep initiating anger sex, sorry for the language but I just want to fuck my feelings away. Idk how to move on and stop being intimate with him. I lost feelings for him. He broke our family and know I have to figure out how to support myself and my baby when all I ever wanted was for our family to be together.

I don’t have anyone that’ll take care of him I still ebf he doesn’t like taking a bottle anymore and I don’t work

How do y’all single moms do it?
