First off, I'm sorry about your situation. Nobody here will be able to judge with any degree of accuracy whether he has a point. I personally would not look at this situation as a technical one; this is a business relationship situation. Regardless of whether there is any grain of truth, the CTO has lost confidence in you.

Thank you for taking the time to respond. > The rest of my advice assumes the CEO (your co-founder) has quite a bit of confidence in the CTO. This is the case, it is in my interest however to remain in the company because my equity is vested, the sooner I leave the less I will get in return, apart from my time, and opportunity cost I invested all my personal wealth.
If he wanted to start with a less-experienced technical person, and jettison them early on -- he could have hired an employee and paid them.
Instead he co-founded with you, as a partner. He was happy to take your money -- you have skin in the game. He doesn't get to shoo you out the door now like a temp.
He also doesn't get to do it via the CTO. He owes you a frank conversation. Also you need a lawyer.
tl;dr: From hearing your side of the story, although the CTO is handling this like a tool, the CEO is the biggest schmuck.
