Ummm, sorry, I disagree.
I loved my late wife with everything I have. I've repeatedly extended my hands in friendship to her family since her death but to them I'm the devil because I signed a DNR order that prohibited them from forcing the doctors to resuscitate my wife. They've said terrible things against me and have even abused my second wife whom I met long after the funeral of my first and have even tried to brainwash my children against their stepmother whenever they visit the in-laws. I'm just happy my kids aren't so gullible because they know their step-mom is a wonderful woman who loves them and treats them like they were her own.
I'm striven to be civil to my late wife's family and have never badmouthed them to my children but it's really hard given the hatred of my first in-laws.
If I was Michael, with all the demonizations, lawsuits, media claims, and threats all originating from Terri's family, I would be mighty pissed at them also.
Edward - there's only one difference - TERRI WASN'T DYING!!!!
My FRiend, please accept my condolences on your loss. Many on this board would rip the legal right for you to determine the proper and dignified course of your dearly departed and give it to a judge. And hand that decision to the parents who have zero legal standing.
But niceties like legal guardianship (or the law in general) mean nothing to many here. I support your difficult decision and wish you and your new wife all the best. I am 100% sure your departed wants you and yours to be happy. Your job (IMHO) is to be so and to raise happy and healthy children.
FWIIW: You should keep yourself and your children away from toxic people, no matter the relationship.
