I think it’s the part about “doing things in secret” that has been misunderstood. Your reference may have borrowed it from the Fireproof movie, or maybe the movie borrowed it from your reference, or maybe it’s just a coincidence.
In any case, in the movie, the husband does things “secretly” for his wife so he doesn’t get the satisfaction of “looking good.” Doing things that aren’t noticed helps him learn to once again love his wife unconditionally and to make sacrifices for her without getting anything out of it for himself (not even a thank you or an acknowledgement). Eventually the wife catches on and notices the change in her husband — for example, she would go to the sink to start doing the dishes only to discover that her husband had already done them for her. Or she would go to sweep up a collection of crumbs under the kitchen table only to find that her husband had already cleaned up the mess. Then, she learns accidentally from a third party that her husband donated a large sum of money he had been saving to buy himself a boat he really wanted to the fund she was raising to get a hospital bed for her ailing mother’s home. All of these things showed her that he had truly changed and that he still loved her, and her trust in him was restored.
It really makes more sense to watch the movie, though.
