I loved the part about the leaves. I think this is very good for someone who has been away from writing for awhile! I think your chose of words was excellent na dthe flow was good also. It's very hard when one person can make or break you. And this poem captures that simple truth. Good work!
This was rather dark. I too have fallen into many pieces before. And I know how hard it is not only to piece yourself back together but to find all of the pieces again as well. And even though you put yourself back together...which takes a lot of time and self devotion...you still are missing a couple of pieces. But those are the pieces that are meant to be gone. Or in your terms...the leaves that are meant to blow away.
I liked this. Even though you haven't written in a while...you still have the spark!
A nice change on lost love poetry. I really like the part about the leaves. I think you have a good poetic mindset with that. But the first part about the shards of glass (though good) doesn't go with the rest of the write.
Just needs a little work. (of course that's my opinion, not everyones .
Also, the last line.. maybe something like < crumbling in your hands< would sound better?
