Reassurance from a friend:

“Of course you are.
“You earn enough to keep them clothed, fed, housed and educated. None of your kids suffer neglect in any of these areas. You not only have stayed married to your wife but manifestly love her.
“That’s about the list, isn’t it? What other qualifications are there to the ‘good parent’ club?
“Moreover, this is not a trivial list. The first item – earning enough – isn’t actually that tough, certainly not for someone like you [Ha!–JD], but there are plenty of men who can’t seem to figure out how to earn enough – or, perhaps more commonly, how to keep enough of what they do earn – to give their kids the decent basics. And the second item is, if the divorce statistics mean anything at all, genuinely difficult for much of humanity.
“So feel free to give yourself a gold star.”

[Derb] I have done so. Heck, I gave myself two. Thanks, buddy.

On the point about marriage, listen to Dr. Johnson:

“It is so far from being natural for a man and woman to live in a state of marriage, that we find all the motives which they have for remaining in that connection, and the restraints which civilised society imposes to prevent separation, are hardly sufficient to keep them together.”
