I would tell this grifter to take a hike and lose my phone number.
Think I’m kidding? I’m not. I’ve done it.
My eldest son and his fiance started pulling the entitlement crap around his wedding.
After he was married, my husband and I ghosted them for 8 months. We had boundaries, they crossed them, we were done. They were the ones who came back but we were prepared to never see them again.
Now, any communication is initiated by them and the wallet is permanently closed.
You could see that they realized the relationship was changed forever. They stopped asking for things, help, making hints. They don’t even dare.
You just have to value peace. Once you do, all relationships are easy to navigate and cutting people out of your life becomes easy.
Hope you’ve got a good contingency plan for your declining years!
