Try to do a non emotional analysis first. An emotional analysis will make you quit at some point. Everyone has a few lows now and then; it only takes one of these to call it quits. Look at the numbers and prospects. Analyze this on the time frame of your needs. It looks, from your text, that you can hang in for six months at the most, and even then with some effort.

Look at the numbers. Is there money coming in? Are there sales prospects in the pipeline? When can the company free cash for your salary? Can the company cut some costs in order to free cash for your salary? The scenario, for a six month time-frame should be clear. Talk it out with your partner. Make sure he knows your predicament.

Then, and only then, look at it emotionally. Can you realistically make the effort? Assume there's a relevant chance it does not pan out. More so if the plans hang in undeveloped sales prospects. It's awfully different if you're about to close a couple of decent contracts than it is if you're just starting sales pitches.

Unfortunately, and any founder will tell you this, outside opinion is very unreliable. Hear from people that have founded companies. Everyone else has a different risk profile. I can't count the number of times I was questioned "why don't you take a corporate job? With your skill level, you'd be a demi-god.". Even other founders are biased. It's truly a personal decision, and must be taken as rationally as possible.
