Oh, no, I've been very close to a few of these situations. One guy was such uninvolved at home that his kids came running when my husband came home, but didn't even bother to notice when their daddy came home. (We were neighbors.) Oh, he was a hard worker, all right--made a lot of money, too. A real nice guy. I'm sure there were many who were suprised when his wife had enough and left. Ah yes, men have responsibilities, but women have choices...I'm amazed at the number of people who are outside a marriage, but think they know what's going on inside it.
It's possible you do, but I'd bet you don't...
