Quote: Define "changes themselves for the better".
MrsNOP, I would define this as "the higher-desire spouse, rather than nagging, or being needy/grabby, or being grouchy/irritable, or even just moping in quiet resentment, instead embarks on a "GAL" program of hobbies, self-improvement, and finds their contentment and humor again. They add muscle, lose fat, engage in rewarding hobbies apart from the lower-desire spouse, while treating them with respect and compassion and being as good of a friend and a parent to their children as they can be. And they continue to speak to their lower-desire spouse in the love languages that they know they need, even though it's not leading to them speaking in yours."
That.
Show me where one spouse does THAT, and it leads to these "and the other spouse will (supposedly) have to change" stuff.
Cuz I just don't see it. And I really do want to see it!
