I hate to be cynical, but most people are going to flake out. Many people overcommit themselves, or just say "yes" because they thought it was a good idea at the time. I've experienced this sort of flakiness - and done it myself more times than I can remember. You sound like the kind of person who prefers the social bonding that co-founders provide, as I do too. However, sometimes you need to go it alone, because most people won't be able to connect the dots the way you do. In most of these situations, my motivation would peter out because there was no-one with which I could share the success. Eventually, I sucked it up and rode on without a co-founder, and now I'm having the time of my life. Startups are difficult, especially by yourself. But the short-term pain is worth it.
