is this a good story idea??????

vamps:edward carlisle bella half-vamp half-human:esme

okay carlisle and esme have been married for over 90 years its been 1 año since bella and edward wedding

one día carlisle and bella tell edward and esme they have been having an affair so bella and carlisle leave together for a año what happens when edward and esme fall for each other? what happens when carlisle and bella come back? what if edward married esme while bella and carlisle were gone? bella and carlisle come back wanting their mates back? what if edward and esme welcome a new addition to the family

yes i know about the story line so there are bella and jasper clubes bella and carlisle and stories about aro and bella o jake and edward please give it a chance i will write it if 2 people say they want me 2 write it
