Being healthy and satisfying my competitive nature on the bike is part of who I am. I am a better person because of the time I put into the bike and the time I put into it justifies the cost based on our income situation
I actually struggle more with the time than the money. Finding ways to balance time spent on myself and time spent on others is hard but I am truly a much better person when I have time to focus and drown out all the other things.
As for the actual monetary cost…every relationship is different, but I’d suggest you be fully open about how much you’re spending on your hobbies. Lying or hiding financial matters is not a good idea in my experience. Everyone jokes about it - but if you are lying to your partner about how much you spent on something you’re setting a bad precedent
