I've been told never to compare my insides to someone else's outsides. Plus, if she's that angry, how could she be so happy?
Believe me, I get it. My H has the world on a string, everything is going his way but inside, he's a tormented insecure mess, I only see it because we get so much time together. That doesn't mean that he wont decide he's happy and roll with it. I guess that is what is hard for us to accept, that we can think they are delusional, nuts, miserable, whatever and it wont stop them. It can just help us to focus on ourselves and hopefully stop comparing.
