IMPO we often want what we think others have. To other people you and MrsGGB probably look idyllic. My H also looks like the idyllic H to other people...but those people don't know what goes on behind closed doors...or in our case doesn't.
For me, I'm not striving for something I've been told should be in a R. I'm striving for something I need to have, in order to feel validated by my partner. Do I need absolute passion in my M every day...no, but I do need validation in a manner that is meaningful to me. That could come in the form of sex, that could come in the form of loving words or affectionate touches. I am not however foolish enough to believe that what is often portrayed in the movies or on television is what a happy M is made of.
I still maintain that "happy", "normal", or "fulfilling" is defined by the two people in the R. What works for you, may not work for me, and vice-versa.
That's just my take on it though Interesting question.
Interesting question.
