In-laws, out-laws or x-laws?

So what do I call the in-laws after the divorce? They will no longer be relations-in-law to me...but they remain aunts, uncles, grandparents, and cousins to my kids. It's a quandry. I have seen some refer to the former in-laws as xmil (ex-mother-in-law), xbil, xsil, and xfil. I guess that will make me an xdil (ex-daughter-in-law). ..Hmmm, sounds like some kind of medication.
