Your in a tough spot, but you should just focus on working on your side project and make a priority; if you can get it generating revenue and/or getting a ton of users you should be able to switch from your current day job to your "side project".

I think that this is a problem that plagues a lot of would be entrepreneurs...and there is no optimal solution.

I'd say just get your family on board with your ambitions; since if you are not able to do that, then it will be extremely hard for you to convince users/investors about the benefits of your product. And once you have your family onboard, and have gotten some success with your side project, you should quit your job....but until then keep your day job.
