The difference in actions between him being skeptical and having no passion is very thin to people like us on the outside that aren't experiencing this first hand. Both case would opt for not fully committing. The answer will be in the details, such as his wording when talking about certain subjects, his mood and expressions when brainstorming and discussing different aspects of the project. Maybe it's a little of both. The point is, it is pretty much impossible for us to tell whether it's lack of passion or lack of confidence that's keeping him from taking that leap of faith.

As far as how you should go about handling the situation, I'm afraid I can't offer too much help as I do not have any experience in this situation. However, I do not think it's unreasonable for you to be pressuring him to call your raise and carry his own weight. The best advice I can suggest is to probably straight up talk to him and explain your concerns. After all, you guys are founding a company together, so you should be able to have discussions such as these as if it's your spouse.

Good luck mate
