If that hypothetical situation was toys over your partner because like if you didn't give up the toys she'd die... Yeah I'd give them up of course, however if it was her saying "You can have me or the toys, but I can't stand your hobby anymore" she can kiss the tip of my weenie because that's a big fat crock of poodoo for women to tell you what to do (or husbands in the reversal, of course). Besides showing a controlling nature it is highly disrespectful and shows absolutely no actual love...
Now, the exception to the rule is if your hobby is detrimental to existance... IE: You go into debt (or debt you're unable to control), you spend grocery money on toys, you freak out on her because you're mad about the Rebel Fleet Trooper sucking... Not that I'm saying that could happen even, just bringing it up.
But yeah if it was just me buying my crap as usual and she just said one day she's sick of me doing toy runs and wants me to quit or she's leaving me then I'd tell her to pound pavement. I've found plenty of women who liked my hobby in the past, and I'm sure I'd find plenty in the future.
Not that my current gf would do that, she's always said what I do is better than crack... I don't know to compare, but I'd think it's at least a step below.
