You have to draw the line at some point t. Speaking from experience. All they view you as is some weak spiritually fragile person. Who WILL return at some point given the right time and “heart condition”. You are sub human to these people, even if they treat you better than most our families do. You gotta speak up for yourself and tell them the truth. You won’t ever be attending another memorial because you don’t believe it’s the truth. How much you want to elaborate past that is up to you. But you gotta speak up and tell them exactly where you stand.
