Sounds like you might be chancing her getting bit by the bug, so beware! Before you know it your golf budget will double and you'll be hawking balls in an effort to keep ammo expenses to a minimum! lol
My wife is very athletic, played tennis in college, played intramural hoops, etc. and has gone to the range with me on a few occasions. She's actually got a fairly athletic golf swing, she could definitely become a pretty good player if she wanted. But she struggles hitting the ball off the turf, which is common for someone who doesn't play. She also struggles putting... can't seem to find the right speed, but again that would come with practice.
The problem is that she is a bonafide workaholic... loves her career, travels quite frequently, but outside of a 40 minute workout after work - she doesn't have much of a life outside of work. She probably works 70 hours per week, if you count the 2 hours per evening that she's doing emails on her laptop. So essentially she doesn't have near enough free time to get into a hobby that requires as much time and effort as golf does. And she's the type who would never enjoy taking up any type of endeavor without the means of devoting 100% effort, so I guess she'll wait until she retires before giving golf any serious consideration.
My buddy's wife plays, she's won the club championship at our club 3 times in the past 5 years... she's better than a lot of guys I've played with, very competitive, hits the ball a long way, has a wonderful putting stroke. I think she's a 10 handicap... they're playing in the husband-wife tournament next Saturday, and I'm guessing they'll win it again, for like the third consecutive year.
I often remind him how nice it must be to share the game with his wife... they don't play together all the time - she has her own group she plays with on the weekends. But they do get out together often and enjoy competing against each other.
He enjoys it, but he also reminds me that while he's obviously happy that she does play - the golf expenses for two people are considerable. She's skilled enough to play the nicer equipment, and no different from him - she's also very eager to find a new driver that might offer her another 10-15 yards. I'm pretty much maxing out what I'm willing to spend on golf each season, which isn't a number most people would sneeze at. I couldn't imagine having a spouse that doesn't just play - but takes the game as serious as I do... it would definitely have an impact on our disposable income!
So I'm not totally upset that she loves her career and has no interest in golf at the moment, as selfish as that sounds. 😉
