This stanza hits home for me.

I didn't feel the same way back then. Yet something happened, feelings for him grew. But I wasn't ready, and I don't even know when. Now when I think back, I regret the chance I threw.

I didn't recognize a friend's unrequited love for me; it wasn't until she moved on that feelings arose for her. Funny, how that works. Nice poem, I'll keep an eye out for more of your post.
