I say "I would like to be frugal now so I can do what I want in 10 years". She stares at me blankly. "What would you do if you aren't working?". Sigh. :(
I think this is the thing you need to settle. She really doesn't understand.
I understand her desire to be a SAHM. I totally do. Be there for the kids more, sick days, vacation etc.
Is that what you want to do? Do you frame it like that?
"Look, things that I like to do are: ride my bike, fix my car, gardening, playing baseball with the kids. I think it would be fun to do a daddy/kid triathlon too! I also think I should learn how to cook, and I'd like to do more house projects myself. I can't really do much of that right now because I'm working. So, how do I get to where I get more free time to do these things? I have a couple of choices:
1. I do them now. I would have to work less. If you were to go to work, even if just part time, then I could do more of these things.
2. I do them later, by either retiring early, or by saving enough money to cut my hours/ do consulting.
Which do you prefer? Can you please help me get there?"
I don't know if this will work or not.
But you are correct - you have different money philosophies, re: the bike.
I personally like the idea of "working extra to pay for things" with side jobs. Honestly, I think it's how my family taught the kids about money. We were poor. There were no extras, so we all had to get jobs. Sometimes the jobs were for "needs" not "wants".
However, right now, I don't *need* to do that, as an adult. We make enough money. We aren't in debt. We have kids. Neither one of us is going to do a "side job". And that is where your wife is coming from, I think. Finally she's in the situation where there is "enough money". "Getting a side job to pay for something" is ... manufactured. There's ENOUGH MONEY. There's no real *need*. What's different is that you two don't agree on how the money should be distributed.
