i never told you

I think your teacher was referring to the gramma rule of using present tense for "habitual" or "constant truth" action, which is usually relevant to verbs after "always, often, usually, never".

For example, we say:
The sun always rises in the East.
A stubborn person never admits his mistakes.
He always gets up every morning at 7am.
He is usually late on Mondays.
In Guam, it often rains in the afternoon.

However, the words "always, often, usually, and never" are also used in circumstances where the "habitual" or "truth" is limited to a specific time frame, for example:

He always got up every morning at 7am until he started working the overnight shift.
Many well known scholars never went to university.
Many well known scholars have never gone to university.
His wife will never forgive him for having an affair with her best friend.
Last year he often went to school late, but he is now always on time.
He was usually the last one to say anything, but now he is constantly talking.

Spelling error in sentence 1: "grammar" not "gramma".

"I never told you" does not have a specific name in Engish grammar, it is just simple past tense, in the context of "I did not tell you, not even once". "never" is the adverb to describe the verb "told", which is in past tense.

I think it should be "I have never told you."
I believe it's "Past perfect tense."
