How do I leave?

My fiancé and I have been fighting constantly for the last year. He feels like I’m always over reacting and acting crazy. I feel like he’s mean and sexist and lazy.

We made a list of responsibilities that we each share. Mine include everything with caring for three children, a household, finances, and working a full time job. His including working and occasionally cooking a meal.

I wish I could verbalize all of the problems in this relationship and why it’s so toxic. I wish I could understand how we went from being deeply in love to just being hateful all of the time.

My goal is to leave this relationship. I just don’t know the best way to avoid all the fighting and yelling and screaming and all in front of the kids. I’d like to just go.
