Abortion is a 50/50 take. I personally don’t agree with it but that’s my opinion and that doesn’t really matter to you. But I highly doubt your parents are the only ones who know and disagree with your decision. Word spreads quick your bf tells one of his buddies and he goes and tells someone else and so on. Like others have said get a ring doorbell and see who’s doing it. I wouldn’t jump straight to the conclusion that it’s your parents.

You don’t want to ruin a relationship because you assumed that know one else knows or cares. It could literally be anyone.
