She is a distant acquaintance, I know him better. They had a brief relationship (him on the rebound) and she is now pregnant.
So they got "together", not living together or even in the same county, but in some sort of situationship.
But I know he is into swinging and sex clubs. She doesn't know. He hasn't told her.
I know it's really not any of my business and I should probably leave it well alone. I don't really want to get involved, except I can't shake the feeling that if it were me or were happening to a close friend then i'd want to know. She is basing a relationship and that of their unborn child on lies. She thinks he's faithful and monogamous.
I don't judge him for how he wants to live his life or get his kicks, but i do judge him for leading this woman up the garden path.
AIBU to say something?
YABU = Stay out of it
YANBU = She deserves to know
