Cadance or Cadence?

Ok, look! It bothers the heck outta me when people spell it "Cadence". It doesn't look right and it deeply irritates me. I only have one follower but if you happen to stumble across this post, for the love of God and whoever share my opinion, spell it 'Cadance". I have her name as Mi Amore Cadenza, with an E. So in logistics it should be spelled with an E. But.. DON'T!! Please! Really, honestly I've never seen the name spelled with it and my simple little mind is much too small to process a new spelling. Don't.
