Between you and me, the phrase "between you and I" grates on my ears like nails on a chalkboard. I hear the wrong version about 3 times as often as I hear it said the right way, so let's get this straightened out once and for all.
Mistakes made with the English pronouns I and me have been increasing exponentially for years. The difference is actually very simple - let me explain it to you.
Me, myself, and I may refer to the same person, but they are not interchangeable. Myself should be the one you hear the least, but it's often used incorrectly in place of me.
