basically Cheryl knows that I put family and the responsibilities that come with that first. We are a lowish income family and i dont earn that much so keeping the family fed, warm and a roof over out head is of course the number one priority... I need the car on the road too so that also comes well above astronomy. but that said,
Cheryl tells me if i want something to just buy it. I guess she trusts me to not make rash purchases that will make everyone else suffer

it all comes down to being responsible

This makes for a very happy relationship
