Is your mother-in-law in ill health, or is there some other practical reason to worry about her?
If not, it is best to have her son tell her the news. You should be somewhere else when he does it. She will likely be upset to have the two of you moving so far away, but all children have to leave the nest at some time. She will become accustomed to the idea in a little while. Perhaps you could arrange for her to visit you for Thanksgiving or Christmas so she will have something to look forward to.
