Jesus Christ some of you really do need to get a grip.
Do any of you actually know what was happening in their marriage before they split?...No, I thought not!
Did he have an affair with anyone? No
Did he/she end their current relationships/marriages before beginning to date each other? Yes
So what is the problem...I suppose it would have been better for everyone to remain in miserable relationships and make each other unhappy for the rest of their lives!
As far as his wife's response goes, I would say fine take the mickey out of the food picture if you really can't contain yourself but to take the time and effort to take the piss out of his date is just classless, pathetic and down right nasty.
