I know Jack, I just genuinely don't see the problem... :c)
Mind you, that said, I read the other thread as well and didn't see the major problem there either.... They had an affair, wife forgave them, they miss the ex... I presume the latter is to be expected and it'll sort itself out in time. My opinions on the wife's attitude or indeed the blokes are just that, opinions... As long as she's in her happy place then I don't see the problem and he'll get over it eventually.
Personally I don't see the point in being with someone just for the sake of being with someone but fair dos if that's what floats your boat....
