Was at a wedding of a former work colleague a few years back. She was a most attractive lass and an outrageous flirt.
Anyway, she invited a few of us down to the wedding. No expense spared etc, it was around March or April time one year.
By that Christmas she was having an affair with another lad in the office (who wasn’t at the wedding). She split temporarily from the husband but they are back together again now.
He’s a better and more forgiving man than me to accept that behaviour.
The trust is broken. It’ll never last or be an unhappy marriage unless he was also doing the dirt, or they have come to some kind of arrangement/open relationship.
