You want out. That's really understandable. This was a really ambitious project that quite a few companies have failed at... Last year I worked on a startup by for about 6 months and just got fatigued and scrapped it. I know the pain of working on a project when the momentum starts to evaporate. But what really stands out to me from your extended post is that it seems like you've learned a LOT from this whole experience. Succcccesssss!!! :) Best of luck.
