I was in the same situation. In my case the reason why the co-founders left wasn't told was because the reason was that they thought their partner was too naive and incompetent to work with. Not something so easy to say straight to the face. In hindsight, I think there was no wrong in feeling betrayed in my case, but at the same time the co-founders did no wrong either. We were too inexperienced to handle the situation gracefully. Break-ups can't be amicable all the time. Everyone has their side of story.
