I left my girlfriend crying because of an argument

I don’t know why but this happened a few days ago and I’m still fucking bothered. I left home and slept in my car for 2 days because fuck her, I’ll be back later. I left my girlfriend of 5 years, 28, who is 9 months pregnant crying and begging me not to leave and I didn’t care. I didn’t fuck around on her, she didn’t do anything bad but for some reason we had an argument to the point where she was begging me to not to leave because she’s too stressed and anxious to be home alone with our first kid on the way. And I still left last minute when she said this and i said “you’re still going to have the kid”. <br><br>We both apologized after, she acknowledged that she was being stubborn and I admitted I was shitty, agreed to counseling, and I promised I’d never do it again but idk. I still find myself thinking about this and wishing I didn’t act so shitty.
