I know this was a sad poem, but I found it absolutely adorable. You found a way to explain this note, which I assume to be a note of betrayal to an affair, and you've turned something bitter into something bittersweet is the way I can describe it.

The flow was natural, and the word sequence was in place, almost as if it could be normal speech which is something I found amazingly put. Well Done, and keep on writing (:

Wow this is really good!! i love it! 5/5!

The detail of this poem was well written.
You allowed the reader to understand what this note consisted.
A strong flow from beginning to end.
Although this poem is a somber subject with lost feelings you somehow place beauty and grace within it too, which is sometimes tough when writing a sad poem.
Keep it up.
