Way to nail that point down, nycindie! Viewing expectation as fluid instead of static makes much more sense.
I had a friend years ago who had an issue with marriage because he felt it came with a new assumed list of expectation and he found it to be an irrational thing to do to a relationship that was working just fine. He described it as "Hey, this relationship is great, I love everything about it... let's CHANGE IT!". His assertion is something I've always agreed with but your breakdown is much more applicable to the standard relationship dynamic. That is to say, he attributed it to marriage, and you are attributing it to simply reaching different levels of intimacy.
