I think I just became a single mom?

My husband has apparently “had enough” of our fights/arguments. We have a 4 month old baby. Idk how to feel or what to do. I told him let’s talk it out or figure something out. But he said he doesn’t want to anymore. How can he throw away the 5 years together and a baby?! I’ve stayed with him and been patient with him when he’s been at his worst (he’s even been physical with me once and I forgave him)

Idk I’m literally shaking and sick to my stomach. Am I rly that dispensable. Looking at my baby makes me wants to cry that she has to be put thru this 💔

I’m at my parents house now (for the past few days) and he hasn’t once come to see baby
