That is awful.
Ugh. How disgusting.
Maybe I'm just sensitive, but this along the same lines as, when my cousin had her baby, she had previously thought about termination. She decided against it, and has always been a great mom.
When Baby was about 9 y.o. Cousin's BIL was talking about some parenting thing, and Cousin gave her opinion, so he shot back "What would you know, you wanted to get rid of yours." With Baby standing right there beside her mother's chair.
Its terrible what people will say. I'm so sorry you ahd to deal with this, OP.
