If this is fraudulent or not is of course very, very important. But from reading your comment I feel there are some weird trust dynamics at play here. My view is that for a company to work you need to have people working in the same direction with a large amount of trust. That means that if you are a specialist in your are I will trust your judgement. I need not understand how you came to that decision. If I do not trust you to make decisions in your area or if you are not aligned with the goals of the company I would find someone else for your role. That's how I think trust should work. That also means that if my judgement in my area of expertise is not trusted I will quickly start looking for something else to do. "If you don't trust me to do what I'm good at I'll go somewhere else or do something else". If I were in your shoes I would not feel trusted anymore and look for something else. You also mentioned that all your shares are vested. I'm more used to schemes where you shares vest over time e.g. you receive 33% of your shares per year worked so you will own all your shares after three years. If this is how your vesting works consequences for leaving should not be that bad. However if none of the shares have vested you should thread carefully. Having been part of a similar situation with vested shares and leaving I know there are compromises to be made. All parts have a lot to earn from an amicable deal that let's you and the company part ways without any bad blood.
