If the wife gives you grief, remind her that she only needs one ring, one watch, etc. Buying the bikes you did cost no more than other hobbies.
Heck even buying custom ... bikes is cheaper than collecting cars like someone else pointed out above. People pay 100 a month for some gyms, exercise classes so the beater/used bike ride and repair is a bargain.
Take up golf and play actively and see what that costs, range 2x a week, then 18-36 on the weekend.
It is all relative.
it is your money/hobby so ya better enjoy it while you can.
