He really is all over the place and his emotions are spinning. I agree, w/HaWho...I hope he doesn't make any major decisions while he's spinning like a top.
He really doesn't want to buy you out because he doesn't want to give you any money...it's all about him and maybe he's hoping that if he tells the staff about the situation, maybe you'll back down on wanting him to buy you out. He's lost control of the situation and now he's going to try to manipulate you and the staff by saying things that may or may not be true at this point. I think he was very disrespectful to speak to the staff or person w/o you being there. Now, you have to do damage control since he's gone again.
I honestly don't trust him at the moment because he's desperate to ensure that he doesn't have to buy you out or take out a loan. Whatever he decides to do, he better sit down w/you and discuss it and not just try to sell the company out from under you.
I hope that you can get the business settled up and leave him to himself to figure things out. Keep your eyes and ears open...(which I know you are doing).
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
