Rain - I posted information about MLC on MB and inpain's pages. Do you want me to copy the links here? I suspect you may be correct, and if so, you need all the information you can get.
First, MLCers don't care about money. They don't care about responsibilities. This is really important for you to understand, because your first priority is protecting you and your children from his insanity.
He will get angry. MLCers are the most selfish creatures on earth. You are dealing with a teenager in a man's body. Everything you knew about him? Doesn't matter anymore. He is not that person. MLC is tied up in depression. They are in pain, and chasing happiness in all the wrong places. They will spend, spend, spend to impress their friends, OW, or anyone else.
That is why you need to fill out those papers asap. MLC doesn't end quickly. It can go on for years. We all want to hear that our MLCer is near the end of his run with it. Sadly, you really should start the clock at BD. From BD, you're looking at an average of 5 to 7 years they'll be temporarily insane. Do you see what I'm saying?
No matter what you do, H will be angry. Right now he believes you are the source of his unhappiness. So, taking that into consideration, protect yourself financially immediately. It is not personal. At this point, it is strictly business. You have a partnership that is dissolving, and you are looking after your assets. Take all emotion out of it, and protect yourself.
