Neruda's "Tonight I Can Write..."

i did write my paper on on  this but i felt that there was more that i could say about some of the parts of this poem. in my paper i spoke alot about how confused he appeared to be through his writing. i discovered another part that demonstrates this. line 11 states "..To think that I  do not have her..." followed by line15 "...what does it matter that my love could not keep her." throughout the poem he has this continuous back and forth like he is pulling the pedals off of a flower. i just wanted to point out another part of the work that displayed his conflict over the way his relationship turned out.
