You have said so much in few words - brevity is a skill many poets do not possess...:)
I read this a few times and then noticed that you nearly wrote a senryu, if even unintentionally. Three lines, 5 syllables first, 7 second, and 5 again at the end. It usually packs a punch when done well.
Please excuse my poetic intrusion, but this is just as an example - please try this at your own leisure:
i settled for him
because i hated myself
hard lessons hurt most
I love to break rules so I also took out all punctuation and capital letters, to stress the vulnerability of the writer.
