Financially it was fine, my wife has a good job. It's far better to have two people living off of one income than one person living off of zero. (I had my own anyway, but even if not, we could have swung it due to that.)
As far as being productive goes, it depends on your relationship. One of my cofounders is pseudo-married and his girlfriend pushes him to work harder. Another has a recent girlfriend who absorbs far too much of his time and mental effort. Being married has no bearing on this, it's all in how you handle relationships.
Also there's more to productivity than the quantity of working hours. Someone who makes you happy (which better be your spouse) increases your output when you do work.
For double effect tell your spouse "There's more to our relationship than the quantity of time we spend together. A job that makes me happy increases the quality of our time when we are together."
I wouldn't focus on explaining what makes you happy if you want this conversation to end well.
Now excuse me while I punch myself in the nuts for knowing so much about a chick flick.
A spouse is kind of like an anchor...that complains every time it gets dragged behind you :P
Anyway, I've found it best to keep my highly stressful occupation and relationships as separated as possible.
I actually think it's a shame that there aren't more women founders. There are many problems that women face that could be solved with software. A single hacker fresh out of college won't think of these problems much less solving them. Even then, single male hackers would be terrible at solving these problems. Theres a huge hole in the software market that's begging to be filled. Having a my wife as a founder is a strategic advantage. She thinks of a lot of things that I would never think of. And, she's worked in high-tech before. I'm career changing.
Besides, we get to work together, which is something that we've dreamed of and worked towards for years.
Yes.
