I rated this a 4/5 because there were a few parts that could have been tweaked a little to improve them a lot. For example, neither of the last two sentences need commas. Also, the last line didn't make sense--proofread it and you might see why.
"They can shatter our hearts.
And rip it in two with the things they do."
This could be changed to have better rhythm: They can shatter our hearts and rip them in two
with the things they say and the things they do."
Consider the changes; they could improve the poem from a four to a five. ;)
