Verse lyrics/vocals + chorus cleaned up

Hey, I need 1 verse topline and lyrics written and help cleaning up the chorus melody lyrics, specifically the last line 'ever walked out on me' its crap. i needa fix it. I left one of the chorus's without vocals, the second chorus has vocals over it. I've written like 300 toplines for the verses, i really just need help with lyrics. everything I write is really cheesy and I hate it.

Additional info:
I will only use the vocals for demo purposes. Not for release.. I need help writing both lyrics and a vocal melody. I'm hoping to find a good singer who can work with my limited budget. I don't have a hard deadline for this. I'm an independent artist not affiliated with a record label.
