That is a beauty. I would love to know the name, but then again, that does not really matter. It is just gorgeous. I would love to get my hands on one of those. The picture is such a pretty color. That is like a salmon with a pink center. I will keep my eyes open and maybe we can find a name for it.
To answer your question, No, I do not have any of my stock/mother plants that want to die but I have a feeling you are watering it too much. Why not ignore it for a few weeks and touch the soil after that time and see if it is dryer than it was. Maybe you have root rot and need to repot it. Does it shrivel up when it dies or what?
