Because I am just steaming about this. The scenario is that two friends of ours are in a long term relationship. He was our friend first and he's absolutely lovely. We met his earlier girlfriends, but he was always a bit non-committal with them. He is clearly head over heels about his current long-term girlfriend. Absolutely smitten. They've been together around 6 years.
So last night, in a moment of drunken indiscretion she chooses to confide in me that she is having an affair with his best friend.
And now she has made me complicit in deceiving him and I DO NOT WANT TO KNOW THIS SECRET AND I AM FUMING!!
AIBU?
