Good luck with sorting this. It is your money, that you earned, and you are not neglecting your contribution to the family finances so personally I'd be tempted to follow Muirenn's excellent suggestion of "Honey. I've decided to get a new bike".

I'm shortly going to sell the very first bike I had, that my husband bought for me, and he has been nothing but supportive as it was a First Bike, bought for me to learn on and to see if I liked cycling (I do). Whenever I worry about spending money on bikes I consider how much I used to spend on gym membership - about the cost of 1 bike every year - and you can't even sell it on second-hand.
