Catch My Sarcasm (Acrostic)

Certain that I'm still in love with you
Always thinking I've yet to move on
Truth be told I'm over you now
Contradicting ass, you're just my pawn.
How I ever loved you I do not know
Must have put some spell upon me
Your whining is now tiresome
Sreeching like some kind of banshee
Abandoned me in my hour of need
Realizing now you're just a waste
Calculating and cold all over
Affected me once, now you've been replaced.
So for old times sake I'll say ''I love you''
Making my sarcasm come shining through!
