though I disagree with you. The Schindlers have been behaving badly for years - not just "the past couple of weeks."
They have allowed Michael to be maligned as a 'murderer'and more;they stood by while fanatics lied about Terri's 'awareness' and prognosis; they encouraged other fanatics in the circus which made the 'dying' of others at the hospice a living hell.They have lied about the tenets of the Church (re matters of death, sacraments, etc.) in order to paint themselves as 'holy' and 'caring' against a 'heathen' son-in-law. They have been shameless in their 'ungodliness'.
If I were in Michael's position, I would take the same steps to keep the Schindler family away. I have no doubt that they would turn any ceremony into another macabre circus - continuing to dishonor the daughter they claim to love so much. That family is in deep need of psychotheraphy - have been for a long time. They need to stop looking at the 'red light' on the camera and search their own hearts.
