Looking for opinions on the below;
My father has been having an affair for a number of years. My mum knows and has known for longer than I have known. She accepts the situation. The affair information was shared with me by my dad but I was told not to tell my mum that I know.
I am now aware that many lies have been told to me for a long time in terms of where my dad is at any given moment. I am furious in a million different ways about this situation.
Mainly what I’m furious about is that I now feel like I am part of the lie and am lying to others on his behalf - eg my kids ask where grandad is and I have to hold the line that he’s gone away with some old friends.
AIBU to let the cat out the bag and tell all to my mum and my kids (they are both older and have left home)? Or should I do as my dad has asked and just respect that this is an arrangement my parents are happy with and leave it there?
