So sorry he is being a D&*k. I agree with SJW. Wait to hear what lawyer says. Would not be happy if he did send response and your lawyer didn't forward it to you. Frustrating.
I totally get your anger, hatred, and disgust towards him. You put out the olive branch, and I assume this wasn't the first time, and he ignored it. But like SJW said and you have before, this is business. This is your future your negotiating. Blah blah blah, be the bigger person, you are growing as a person, blah, blah, blah. All true but let's state the thing we aren't supposed to say. He caused this mess. You don't deserve this. Yes, they (MLC) are truly suffering, etc. But they have an adult enough brain to function in society so there really is NO excuse for them to be so selfish that their needs come first and they are selfish for not dealing with whatever issues they have and in fact causing innocents to be collateral damage. You can be mad. You have every right. If we didn't know them before and how wonderful they WERE we would be swatting them away like a fly.
I also think he probably didn't know how to respond to your letter. In the back of his mind he knows you can blow up his career.
So dear, Treasur, rage and get it out and then be kind to yourself. Go take a walk on that beautiful beach and feel the sun. Buy something for yourself. It doesn't have to be outrageously expensive: some nice chocolate; the super venti caramel, mocha choca coffee something; or, a goldfish! You get my drift. Look for signs the universe is good and I bet someone will contact you out of the blue and change your day. Or, get in the car and come see me!
You'll get through all this. It can't be as bad as BD. Maybe his behaviour is to help you detach utterly completely and then you can proceed without remorse.
Hope that helps. I am always afraid I am going to get kicked off. I am routing for you.
