Dear Queenie,
My sister faked being pregnant to keep her boyfriend from splitting up with her. She even gave this fake baby a name, which her boyfriend has in a tattoo on his arm. He moved in with her because of the (fake) baby and after a couple months my sister pretended to have a miscarriage and now she talks all the time about how much she misses the baby she never had.
Queenie, I know the truth, that she was never pregnant. Should I tell her boyfriend?—Liar’s sister
Dear Sister,
Your sister may have acted out this lie so much and for so long that she has started to believe it herself, or she may be keeping it up in order to hold onto her boyfriend. The man has a right to know the truth, but prepare yourself for the effect this may (probably will) have on your relationship with your sister.
And try to persuade your sister to get professional counselling for the way she is behaving, which is not, by far, what I would consider normal.
