This type of situation is very simple. You guys must draw th line in the sand upfront. My old lady knows there are a few things that are not negotiable:
Fishing
Hunting
A/V

I know there are some things she has/does that are not negotiable either.

That being said, you have to be reasonable about it. She knows the stuff that is not negotiable, but at the same time I don't abuse it by going nuts in those specific areas either. She does the same.

At the end of the day, it's not about ***** or some ridiculous game. It's about mutual respect for each other's passions and idiosyncracies. If someone is asking you to change who you are (i.e. not "allowing" you to buy the A/V stuff that makes you happy, within reason of course), then I would suggest having a "sitdown" and revisiting the entire relationship because that's a harbinger of trouble ahead...
