NC.
I grew up in a single parent family. My mother (who is extraordinarily selfish) only ever gave vague details about my father and claimed to not know where he lived, what he did for a living, what other family he had. Whenever I mentioned wanting to know about him she'd get frustrated with me and say he was "cunning and crafty" and she doesn't know anything to tell me so I need to drop it.
When I was in my 20's I discovered, by complete chance, that I have an older brother who was given up for adoption at birth.
He, like me, wanted to know who his father was but our mother claimed she doesn't know anything about him and can't even remember his name. We know we don't share the same father as me and our mother are Caucasian but my brother is not.
At first she said she met his father when she was working at a certain place, then later changed her story completely as though she'd forgotten what she'd said, as she then said he worked somewhere completely different.
AIBU to think she is deliberately withholding information she must have, from the pair of us?
How realistic do you think it is that she got pregnant to two completely different men she knew nothing about?
