If a man calls you cherie does he want more than friendship?

It's possible or it could be said as a joke - it depends on the context.

If he's French, it could just as easily be a friendly remark as an endearment. It probably isn't a joke.

answer 2:

No, it's a friendly way to say: honey, darling, sweety... You can say that for a friend :"Hey cherie, how are you". Or a mommy to her child :"Good night cheri". But it can be used for a lover too: " Je t'aime (ma) cherie"

it is possible to use "chérie" only with a lover or a child otherwise it is rude. Only bad man call an unknown woman "chérie"
