I was actually going to go AU at some point--so the premise will be, what if Piggy had gotten her life together and it had only taken like--two years? Then when Kermit sees that she really can live without him, he'll finally realize that he can't live without her. I honestly believe if Miss Piggy hadn't been in Paris, he'd have caved a lot sooner. He doesn't really want to be without her, he just can't quite reconcile (rationally) being with someone who is so dramatic and brusque and bossy. He often seems embarrassed about being with her, not--as she assumes--because of her so much, but more because he is intensely private and she is definitely not. I think he really cares too much about what other people think.
