Nope. If it comes back Fry proposed with the button, the Professor said it would go back to before the button was made.
He was already planning it though, so there's that.
Not that it matters anyway, they already got married and lived a wonderful life together. The reset button doesn't ruin that any more than the fact that Leela isn't even the Leela that Fry originally fell in love with. Not so long ago, he traveled forward so far into the future that the universe ended and re-started. Then he did it again. Then he killed the Fry that was living there and took his place.
Loved the finale. As I have done twice before. (Hmmm...)
I'll miss you Futurama. Again. I will avenge you!
