In addition to what they said above, you put way too many questions in this poem. In fact, the whole poem is a long, unanswered question about why you love this person. Instead of just saying "because you are: you!" show us why "you" is so important to the narrator. What does "you" do/say that's so great? How can you show that special quality in a poem that's interesting and will actually capture a reader's attention?

Best of luck in future writing!

Hmm...it's a bit repetitive like Siegfried said. The idea of having "young" and then "older" two lines down sort of confused me. I'd look into changing that. Basically I agree with Siegfried. Grab a thesaurus to help you with word choice repetition.
also something about the colon in this like

Or simply, because you are: you!

Again I say like with one before you concentrate on repetition too much. These poems if less repeative be good, just try a poem like less repetition and maybe more variety of wording.Good Luck and please try listen to advice.
