Apple had a version of this problem (45/45/10). After much less time than 18 months, Cofounder Ron Wayne cashed out his 10% of Apple for $800. Are you at peace following Ron's path? One other point is the notion that you're in the process of raising $500k. I, like many of us, have been in the process of raising hundreds of thousands of dollars for many years, decades even. Most years, there was definitely process but the only result was a donut between the $ and the k. We don't know your finer details, but there's a good chance the entirety of the firm is valued at zero and so is your sunk cost of time. So it's not worth stressing over what percent of zero you manage to walk away with. Keep in the loop, slack off if you must, and pick a better moment (better than immediately before your hard work pays off) to walk away.
