This is the first poem i have written. Constructive critiscism is welcome

I love how you expressed feelings..and how you love that person but never told them how you felt..loved it!
5/5

I never told you I loved you
As my intention was never to.
It was just something that happened,
But it as a feeling I haven't abandoned.
This mistake fills my heart with sorrow;
For I know, with you there is no tomorrow.
I can't help but feel cold
because my love for you I never told .

^ I'd just insert the punctuation I added up there; it makes the poem flow better and will make your thoughts clearer to the reader. I like that you start the poem in a similar way as you end it, that gives the poem a specific structure. I think that the emotions are strong and heartfelt, but you could of written more. Overall it's a well written poem, especially for this being your first one.

Thanks a lot. English is not my first language so I appreciate your corrections! :)
