If a girl calls me "darling"?

Anonymous
So me and this girl have kind of a sarcastic/playfully mean relationship. We are not exactly friends but we talk and tease each other a lot. Yesterday we were "arguing" and she called me darling. I know it probably doesn't mean much but this isn't a word she uses to call other people or even in everyday chatting. She calls everybody by their.names, except me, so that word kind of stuck out. I know girls use those names a lot but she doesn't use them. Also I noticed that recently she has started to make a lot of eye contact and smiling and giggling and kinda wearing more makeup, fixing her hair and stuff (we've been coworkers for months and I've never seen her like this) could something be up?
