It was my baby neices christening when all the family got really merry, my dad in particular. When i was going to get another drink, he randomly said that he's gay and couldn't bare his life with my mum and started laughing. I tried to ignore it, but the next day i asked him if he remembers anything from the night before and he told me not to repeat anything he said.

So this means he was telling the truth right? What will I do? Should i tell my mum? I dont want my family being torn apart ='(
