I'm looking for stories where a married couple go through a divorce for whatever reason, maybe adultery, maybe something else, and because of the divorce they're forced to continue communicating. The husband would then make some sort of change for the better, like get in better physical shape or do well at work to the point where the ex-wife would be curious. Maybe they get back together, and maybe they don't. But the basic premise would be the that a husband goes through a self-improvement journey sparked by the divorce. Thanks in advance!
