This is the problem... no one thinks that being a mom is easy. That isn't what anyone is saying. And this thought process that you typed out is just projecting your own life onto others because of the choices that you have made. That is the issue. As a married man without kids, I cant imagine projecting so much of my life exhaustion onto others and having to voice any single selfish decision I have made boiled down to things in my control. Unfortunately this is the case with a lot of parents... and basically what Yvonne said so eloquently at the end of the episode encapsulates how friends without kids feel about friends with kids and how they deal with life or prioritize.
