A Successful attempt?

My first sad poem i dont like it much the title realy isn't so great so tell me want you think

I don't know why this feels bittersweet
I was the victor but I feel a defeat

I fought fair and overtime for such a bounty
What I'm feeling I could not foresee

I got close to her friends hoping for aid
I needed a good start for this crusade

I engaged in reconnaissance
Observed that she already found a romance

She had no interest in me and my endeavor a failure
I was prepared to give in and wave the surrender

I figured I'd tell her, she deserved to know
How she captured my thoughts and my mind wouldn't say no

I wrote what I felt and gave it to her
A response could I endure?

My words had quite the effect
"He" was soon made a state of neglect

She gave up on him and turned her sights on me
But still no feeling for a victory

Can I feel in my heart
Somethings missing an important part

I search deep inside and hope for a solution
Perhaps I thought he'd come for retribution

It was a success but still is something wrong?
Somehow this event just cant belong

I will attempt to remain positive
Lets hope this relationship isn't defective
