I still don't know about the five LL's... Particularly if there's an affair going on I don't have much confidence in that being a useful tactic... To me throwing a cheating spouse compliments just smacks of affair validation...
She cheats and you throw her compliments... SHe's gonna cheat more.. But I could be wrong...
My reading of 5LL is that its a useful tool for building a willing marriage, that is both partners are activity working on improving things...
But if one is wayward, or worse having an affair I don't get how using that NOW is sending anything but the wrong message...
