Let's see, I made 5-6 times the income my ex did, I worked double the hours at my job compared to the hours she worked, I did all the outdoor (read men's chores) before and after the birth of our child, I took next to no time off for paternity leave, I took care of our child as much as I could when I did get home from work and I continued to do all that stuff when, after the end of her paternity leave, my ex decided "she's just rather stay home with the baby". 

Oh yeah, then she started sleeping around while I was working and left me (after I caught her) for a guy who made a 7 figure income. 

My point is that every couple is different and BS columns like this from Leah make these ridiculous and sexist generalities about what's going on again and again. I used to like her writing but her head is now firmly where the sun doesn't shine.
