Analysis of A grace i had

i remember when she turned around,
her face in pitty and sad she sound,
when she said good-bye,
my body was taken over shy,
it was not easy to let her go,
but it was best idea to do so,
she loved me and i felt that splendid love,
for me it was hard to return what she deserve,
my fault i embraced her to comfort,
though i knew i had no feelings for her,
i used her love for myself,
i thought no one would love me in ma life,
i didn't want her to get hurt,
i broke up with her just like that.
