Makes me wonder why I even bother to be a decent human being.
Ummmmm because actually that is what we are put on the planet to be??? Maybe your journey is to figure out who you are and who and what you truly want to be. Put the focus on yourself.
And on the books front, if your wife is actually reading self help books then I would suspect she isn't in MLC. Most, if not all, MLCers think there is nothing whatsoever wrong with them.
The idea of my xh reading a self help book makes me smile at the sheer unlikelihood of it. He genuinely thinks [or used to think] his family are nuts, and we all need help.
