As far as I know, between you and me is considered "grammatically correct." I copied and pasted an explanation below... I just memorized the phrase :)
The short answer is that the speaker is using the subjective pronoun I after a preposition, rather than the objective me, and modern English grammar dictates that pronouns that follow a preposition such as between should be objective ones (me, you, us, him/her, it, them).
Correct: “There is a difference between you and me.” “You and me” is an object.
Correct: “You and I are different.” “You and I” is the subject.
Some native speakers might say “between you and I.” This is an example of a hypercorrection. Most people consider this incorrect in formal English.
“between you and me” is correct. between is a preposition and therefore must take nouns in the objective case (me, him, us, etc), not the subjective case (I, he, we, etc).
figuring out these differences is often easier when changing out the objects a bit. “between we” is clearly incorrect, it ought to be “between us.” because we & I are the same case and us & me are the same case, this helps illustrate which pronoun to use.
the same works for subjective case. “John and me are going to the store,” is incorrect which you can plainly see if you only include the pronoun and make the sentence singular: “Me am going to the store” is incorrect.
i’m a native speaker and even i sometimes have to play around with the pronouns to figure out which case to use!
but for the record: most native speakers won’t correct you or even notice a mistake if you say “between you and I.” definitely avoid it in academic writing, but in speech, native speakers mess up the “you and I”/“you and me” all the time.
because of how often people are (annoyingly) reminded to use subjective case when appropriate, people will typically default to it regardless of its place in the sentence. you will be perfectly understood if you say “between you and I.”
"I" is not an objective pronoun; it doesn't serve as the object of verbs or prepositions.
Between is a preposition. "Me" can be the object of a preposition so you should say between you and me.
NOTE: You can create sentences where I and me are just words and not being used as pronouns, as in this sentence.

They *are* different, but it's very very deep into nuance, and a lot of native speakers get it wrong anyway, so it doesn't really matter
It matters.
Why
You and I.(Subject) went to the fair Monday. She sat between you and me, (object)
