Biggest tip, don't marry one that is going to give you crap about something that truly makes you happy. Real love doesn't do that.
Of course you have to be responsible with it too. As others have said, do not ever put this or any hobby above your family. Don't spend money on a hobby that is needed elsewhere. Make sure to support her hobbies in return, even if you think they are silly. If there's a pin she loves, make sure she gets it so she can be a part of your hobby too.
The ones that make being in this hobby painful for their husbands are probably the same ones that spend more money on makeup and shoes than a pin costs per year. I really have no patience what-so-ever for people that supposedly love each other, yet "forbid" things that make them happy if it is safe and financially responsible to do.
Remember guys...marry responsibly.
