My husband’s story is not unlike yours with his daughters from a different marriage. He worked himself to the bone but believed he was there for them, but when grandchildren came he was far away. He tried but they didnt invite him to the many daily wonderful events and he didnt want to impose so didnt beg an invite. . He now lives in a nursing home with ALZ, his daughters barely check on him and his grandchildren don’t have a relationship with him. I moved from the south to NYC region - uprooted the two of us to live close to my daughter and grandchildren. It’s been a challenge for me personally, but when my daughter begs me to visit and my grandchildren give me hugs as their nana - I learned that this was living. Nothing is better. My husband has none of it, and his is a sad and lonely ending.
