A simple way to know which pronoun is correct is to transpose the pronouns or the clause:
Don’t let anything come between you and__.
Don’t let anything come between me and you.
Note: ‘me’ is the object of the preposition ‘between.’ While it may be impolite to refer to me first, at least it’s not incorrect grammatically!
Don’t let two pronouns confuse the case – eliminate one of them and then say it:
Please let him know this came from you and __.
Please let him know this came from me.
Note: You would never say: ‘It came from I.’
Consider this famous gaffe form Jim Morrison and The Doors:
“Let the stars fall from the sky, for you and __.”
“Let the stars fall from the sky for me.”
Note: A word is not correct simply because it rhymes with another!
