My sister had her baby about 6 months ago. To this day she hasn't told our dad he has a grandson! She lives in Switzerland so barely see each other but still.
The reason why is (and bare with me as it gets complicated here) my auntie (so my father's sister) is claiming the private pension of my uncle (my mother's brother) as they were once married bit never had a financial settlement. My sister was named the beneficiary but my auntie has been able to claim instead.
My DM and sister are annoyed with my DF and this haven't told him about the baby. My DF just days that he's caught in the middle and rather not get involved but if she wants to prosecute/press charges he has her blessing.
Whenever I talk to my dad o can mention my nephew because to him.he doesn't exist. I'm having a baby myself due in a few weeks so any potential family reunion has been wrecked, thrown out the window. (I know I'm being selfish about this last point).
