If you eventually get your doctorate, then why can't YOU be the primary breadwinner? I asked this before and you didn't respond.
You mention children, but you will find it VERY difficult (almost impossible, actually) to be a responsible parent AND a successful academic without the support of a partner. Based on your career trajectories, I would suggest he stay home and raise children, and bring in some extra income from a home-based business. Technician sounds like he's in IT and a lot of those jobs can be done by telecommute. I have a friend who does this; she is a professional who works out of the home and he stays home running his business (he's a web designer) looking after the kids during the day when she is out. Works for them.
Unless, as I said, you are looking for a reason to dump him that is not about money. In which case, you should be more honest with yourself and him.
Good luck.

Second thoughts can generally be amended with judicious action; injudicious actions can seldom be recovered with second thoughts.
