If you are not a parent, and especially, if you are not a single parent, then you have no idea.
I took care of my kids for well over a year, well over a year while my ex-wife was fuqing around on me. She had multiple affairs.
I hired a private investigator, my dad actually helped me pay for it....for months. I put a GPS tracker on the back bumper of this cheating, lying, whoring woman's car, and they followed her, for months.
She should be emabarassd, truly embarrassed at the places she visited and where she went and the men she saw. Sweetie if I was you I'd change my name and move to a different fuqing country, I really would.
But the most embarrassing thing, the thing that I hate to tell friends about is the way you neglect our kids. It is just....embarrassing.
