I'm married 37 years to my High School sweetheart. She'll joke about my spending on my passions, years of endurance racing had me spending on bikes, running and swimming gear and race entry fees. Now back to fishing after an absence for my racing "career" the spending has shifted back to gear.
My wife spends on her hobbies and clothes.
Years ago we decided that we will not ever argue money as long as it doesn't impact our quality of life. We share all bank accounts. Through our 37 years of marriage we have gone back and forth as top earner. I'm not out drinking, getting stupid and staying out late for no decent reason.
She loves that investing in my passion makes me happy just as when the girls are all over to play "Mahjong" and talk crap about the hubbies I just smile and say, "Honey, I'm goin' fishin'."
