Like others are saying, in Britain where it's common but it's barely even a term of endearment, more likely they forgot my name. Here in the Netherlands I very rarely get called love, sweethear, dear. I think it's considered very sexist these days? My family also very rarely use the terms although I look for "I love you" at the end of a message or card, especially from my son. With family (son, siblings, parents) I'm guilty of convincing myself that they hate me or can't be bothered with me.
