It is nice that you can drop to one full time income, but I recommend you at least try to keep your skills up to date, to help keep the pressure off of her by knowing you are ready to dive back in.

I left tech completely for 5 years, to make gears, which was rewarding, I stayed because I was part of a 4 man shop, and it was nice to not worry about servers on the weekends, etc.

My wife's income took a hit, and now I've been out of tech for far too long... nobody programs in Pascal any more.
