My family dinner exploded into a shocking inheritance betrayal, leaving me heartbroken and lost. At 45 with no kids, I’m apparently a “problem” for my 72-year-old dad and his new family.

Dad’s leaving his entire estate and our childhood home to his stepdaughter (whom he raised since her teens), who has four kids. My stepmom justified it cruelly: “It’s not like you have children to raise!” I stayed silent—until after dinner.

I stood, announced I’d secretly recorded them, and played the audio. Silence. They were plotting to manipulate Dad into signing over the house, then dump him in a nursing home.

Dad went pale, realizing their betrayal. I told him: “If this is the family you’ve chosen, live with it—without me.” I walked out.

Now he’s begging to reconnect, but my heart’s shattered. He chose them over me just because I have no grandkids.

Am I wrong to cut him off? What should I do?
