Never been an issue. My wife has supported my hobby 100%. She almost never plays. The only time we have much of a discussion for me to explain some move is when I want to sell a pin.
She even makes sure we keep cash on hand for the inevitable late night decision to road trip the next day for a sudden purchase. Never gripes when at the last minute I tell her I need to run to a buddy's house to help with repair or to see a new pin.
Honestly, I cannot recall a single time this hobby has created any conflict in our marriage (29 years). I am truly a very lucky man.
