One man has reportedly just found out that he and his wife, the mother to his three children, are half-siblings -- but he has yet to tell her the news.
In a letter, a husband reveals that he and his wife were both "born to lesbians" -- he to a single woman and she to a couple.
Unlike his wife, who'd met her biological father when she was 18, the man never felt the need to find his sperm donor until recently. His findings have left him in turmoil.
It turns out, his mother and his wife's mothers had gone to different sperm banks, but, as the man writes, "it appears so did our father."
He describes his anxiety in telling his wife and even that he is considering keeping the discovery a secret.
"I can't help but think 'This is my sister' every time I look at her now," he writes.
Because the writer is anonymous, skepticism surrounds the letter. One reader suggests that the story is "a fiction pushing a political agenda."
