Cheaters Never Prosper

(This is sort of a Negan/OC character but she is based off of myself so more a Negan/Author fic)

It is pre - apocalypse at first and Negan is cheating on his wife Lucille with other women but meets a young woman named Isabella through online gaming on Xbox Live. He starts to fall in love with her while trying to deal with high school students and his dying wife. How can he come to terms with everything while the zombie apocalypse is upon them and how will he get to Isabella?
