OP it means she is friend-zoning you.

I don't even like my fellow ladies calling me "dear" "darling" "sweetheart". I feel they say it to make you feel inferior to them or younger or just not up to you in one way or the other. I cannot seem to explain it but i don't like it especially if we don't know each other.
