Solid advice with one exception: you may not be able to make a deal that makes your cofounder happy.<p>Even if you&#x27;re as nice as you can be, make good, on promises, etc, you may still end up being &quot;the bad guy.&quot;  Emotion is the enemy of rational thinking and there&#x27;s going to be a lot of emotion here given the commingling of your personal and business investments.<p>You have to evaluate your behavior on the clarity of your own conscience, not on the communicated perceptions of the other party.
