I agree, it is very hard if you are trying to convince a SO that doesn't see or understand the connection between your passions and well being. It's also very difficult if your SO has already decided in his or her mind that it has to be either or (them or the startup). It would be awesome if there was some guide or handbook on this subject, but there is no easy answer to making your SO understand.

It is possible to have both (your passion and your SO) if you can find a balance that you and your SO can both live with, and maybe that's the easiest way to help your SO understand...by including them in that process, and making them feel like you guys are figuring it out together.

In the end though, there is only so much you can do/say to try and convince someone who has already made up their mind that your logic is bs. At which point you should probably let that person go, so they can take a dump on someone else's dreams, lol.
