I married an "enabler"!
If I see yarn and say "oh look how pretty!!!" he'll say buy it. He actually was touching some expensive cashmere at a yarn store on vacation one time when I first started knitting and said to me "I like this, you should buy it".
I have to tell him I don't need stuff. He's pretty darn cool about the knitting habit. Of course, he's got his models trains, antique cars, mountain bike stuff, etc. and all I have is my knitting so it's not that big of a deal compared to his expensive hobbies.
