You should get out now -- you got some experience building a project and got paid some for it. From personal experience, it's likely your "co-founders" will continue similarly as before, causing you additional stress. Until the exact details of the 1/3 agreement are in writing there are innumerable ways you could be screwed, especially since your co-founders have shown they are untrustworthy. I understand your point about 1/3 being better than nothing. However, 2/3 of the stock being tied up by do-nothing founders will prevent future funding. It would be better for you to use your experience here to make an even better product with new founders.
