Think of all the
bikes you could have bought with all the money you wasted on a house and transport for your family. If you all cammed into a bedsit and ate out of dumpsters, you could ride all you wanted.
I'm sure there's no way you at all benefit from the house or car, or from being a provider to your family.
In my less sarcastic counterpoint to some of the drivel above, I'll say this:
My wife hates bikes. She tried various safety, etc, arguments to get me off them. Didn't work. Then, we needed cash for a house. We then needed a car, and a second car when my son was born. Providing a house, car, and holiday time to spend with my family is more important than owning a bike. I still have mine, but its in bits in the garage as a project I never have any time to tackle. To keep a riding fix, I do off-road school type days (try it even if you don't have the war at home).
You're a husband and a father as well as a biker. That means something. When you have the cash, then look for a bike. But, you might have to give up other stuff (pub night, season ticket, whatever) I did. And you may also might want to think about this: does your wife spend multiple thousands pursuing ahobby that is only of benefit to her. Or does her money go towards family (compromise) needs too? If the answer to that is she blows a load of cash on herself - you have an argument. If not, you might wanna think some.
