Could things get any worse (just need to vent)

Madely • 22, Mama to a baby girl 💗

I’m a Sahm with a 4 month old. recently had miscarriage and now my SO cheated on me. Right before we made 5 years together. How could he do this me. Mainly to her, I am so heartbroken.

After I found out he said he won’t be saying sorry since I cheated when we were 15.

I don’t know what to do, I grew up in a broken home. I don’t want my daughter to go through that.

UPDATE: I decided to leave him for the sake of my babygirl, thank you ladies!
