Not that its a justified excuse, but no doubt some of these men have come home from living in a hellish dung-heap for months, getting shot at frequently, only to find that their wives had a revolving door installed in the bedroom while the husband was gone. Happens a lot when soldiers are away.
Or weak-willed women find they cannot hack it because the husband is away for long periods and they have to manage the house/children by themselves, sleep alone at night, boo hoo I was lonely, etc. though they knew what it was all about before they got married.
I would be pretty furious if I had just spent 3 months in some hell-hole getting my ass shot at only to return to a wife who gripes about how horrible it was running out of her favorite bon-bons she likes to eat while sitting on the couch watching The Young and the Restless.
