Is there 2 different series of Alice?

I read “I like him he likes her”, I do not know if I need to read the other books. Is there 2 Alice series. Do I read “Now I’ll tell you everything:?

It can be a little confusing, I know.  There is only one Alice series, 28 books, and each book is published both in hard-cover and paperback.  Because the books about Alice in high school were so popular, the editor decided that after these books had been published in both hardcover and paperback, they would also bind up the three books of her freshman year into a very thick paperback, and do the same with the three books of her sophomore year, junior year, and senior year.  And then, because the final years of Alice cover so many pages, that would come out in a final thick book all by itself.  So I Like Him, He Likes Her is the bind-up of Alice’s freshman years (the books Alice Alone, Simply Alice, and Patiently Alice). “It’s Not Like I Planned it this way” is the bind-up of the 3 books of her sophomore year;  Please Don’t Be True is a bind-up of the three books of her junior year, and You and Me and the space in Between is the bind-up of her senior year books.  Don’t read Now I’ll tell you everything until you’ve read all the others.  Enjoy!
