Are you sure your resentment is really frustration at her and not frustration at the state of the business? Your lack of salary or funding? Or how difficult you are finding it to reach customers? It sounds like she is putting in the equivalent of a fulltime job. So while its easy to transfer your frustrations onto her ("these problems would be solved if you put in 70 hours like me"), you might want to be careful you aren't giving in to wishful thinking. Certainly, if you are putting in 70 hours and that isn't solving these issues asking her to do the same is not necessarily the right approach. You need to be able to think clearly about why you are feeling what you are feeling, and look outside yourself to figure out if the demands you are putting on yourself and other people are really reasonable.
