Which is correct you to or you too?

“Love you too” is correct and “Love you to” is incorrect. “Too” means the same thing as “also” while “to” is a preposition and part of an infinitive verb in English. I love you. I love you too.

Is it correct to say you too?

You, too has two primary uses, and the meaning of the phrase depends quite a bit on punctuation. When followed by a period or exclamation point, you, too is used as an answer to someone’s general good wishes.
