Significant other leaving me because I don't make enough money for her to not work

The title explains all. I am being left because she doesn't want to help financially, equally (which means her getting a mindless retail job, part time). This helps the family because it saves me grinding it out 80 hours a week, and because I am very efficient caring for the kids needs.

It is a cake walk for me (not for her) because I don't helicopter parent and do the on-demand entitled parenting thing (ie. Kids have chores).

I honestly don't feel that raising kids is that difficult. Not to say it's not challenging per se, but I run a household like a cake walk because I am very organized.

She acts like she has so much to do (that I don't account for) when in reality she listens to her mother, who is the demise of our impending seperation.

In summary, raising kids is like coasting in the sunset with a margarita in my hand because I know how to "say no" to kids that think they are entitled TL;DR
