In my case, my MLCer moved in with his family, and rebuked all responsibilities. Said he would pay "when he could" at random times, which was idle talk. Any arrangements you settle on, it wouldn't hurt to get something in writing, even if it's just a separation. I know that doesn't sound like paving the way, and there ARE some MLCers who are solid with making sure their share is taken care of...but they are few, and the nature of MLC has them changing their minds on a whim, so for your own security, do what you need to do.
