It pains me to read about women like this. 
My girlfriend (of 6.5 years) has always been cool with regards to my audio obsession. She respects my passion and has grown to appreciate the higher quality sound we enjoy around our home.
Had she not been so cool about this when we were first dating that would've been a total deal breaker.
Yeah, she's a PITA. When I told her I wanted to buy a pair of LS6 cabinets from AV123 she said ok.
Then I told her I wanted to buy the speaker kit and she said ok.
I used to own a old Toyota Celica. I complained that it was getting old and what I'd really like is a Mazda RX7 (93). She said why don't you just buy one?
When the TV started going out in the family room I was planning on limping along for as long as I could. She said I should just go out and buy a new one. When I picked out a top of the line plasma her comment was "When can we get it?".
Yeah, she really is a PITA.
To be happily married you must be willing to compromise. When she decides that she wants something a certain way I have 2 paths. Fight it and be unhappy or go with it and be happy. When I make her happy, she makes me happy.
