I think what is important for you to walk away from with this is not the thought this one demonstration will wake her up and win her back but it simply plants a seed. You have not fallen apart, you had the place looking good, you were a good host (something that she probably felt was hers and you would fail without her... hence the statement about you being the party planner all the sudden) and you demonstrated some chaps by not allowing her presence to effect you (outwardly).
Thats a good start to planting several seeds without her realizing how many seeds you are tossing out there.
