Cemar, I can name two specific examples where your theory doesn't hold water.
1) My R with H. He and I have extremely similar spending habits. Money has NEVER been an issue for us. I've already elaborated on the specifics of our M problems. H's spending habits have not changed one bit during the course of our R. And you all know how sex-starved he was.
2) My parents' R. My father was financially irresponsible long before he met my mother. He lived at home with his parents until their marriage (he was 29) while mother was on her own from the time she was 18. At the time of their marriage, she had more money saved than he did. My mother may have driven him to a number of things, but financial irresponsibility wasn't one of them. I suspect, however, that he had been more financially responsible she would have respected him more. She definitely always viewed him as another "child" she had to take care of and on whom she could not depend.
I believe that a person's spending habits are formed before they are an adult. I just don't believe that being in a bad R or M "causes" people to be financially irresponsible. IMO, a person who is a spender after a sexless R is a person who was a spender before the sexless R.
