Advanced Details: “between you and me” or “between you and I”

You must say “between you and me.” “Between you and I” is incorrect because the word “I” cannot be the object of a preposition. (NB: The word “between” is a preposition.)

You should write: It’s “between Boonlert and me.” When we use a prepositional phrase, we need to use an indirect pronoun (ex: “me”) instead of a direct one (“I”).
