Ugh I feel sick. The OW is now calling the father in law "Dad" and is arranging private medical care for his heart condition. Wish they still didn't cause emotional reaction in me.
I think, sad though it is, that will have to be it in terms of contact with the FIL & BIL. That saddens me. But she's obviously ingratiated herself completely into their lives now, and life is now all about preservation of me.
Reality is that which, if you don't believe in it, doesn't go away.
