I would never cooperate with her. How much do you get for this business in partnership mode? Are you a partner because you can't afford to share the risk? Or do you know less than her? Does she advocate you to assist this kind? To do business, you must know enough about the market. What you said is correct. But she vetoed it because of some travel expenses, which only shows that this person deserves to do a small business. What you described is right. Short-sighted. Since we have all had unpleasant experiences before, and I don't think you can control her and convince her, we still don't want to do this business. Failure to do it well is a hassle. Doing it well is another hassle. I used to partner in business because I chose the wrong person and finally missed the best time to do it. My friends are gone. I hope you will consider it comprehensively. I wish you success.
