I wasn't a articular fan, and don't know all that much about them, but they were a fairly successful group, weren't they? Of course its up to them if and when they stop singing, but it seems that everything that has happened to them since has nothing to do with them, and everything to do with their husbands choices and behaviour. I don't think the life path of ex boy band singers depends on their wives.
Maybe somebody can correct me if I am wrong.
Maybe its just media bias, or something
