I have an idea
Carlisle x Esme x Charlie au
In this au instead of Esme's shitty canonical husband during her human life Esme marries a man named Charlie Swan, a man she was happy and in love with. I'll have to play with the timeline a little bit.
Charlie and Esme met when she moved out west to become a teacher despite her parents wishes.
Their romance was slow. Esme wanted to fulfill her dream and Charlie had gotten out of a bad relationship before this. They started as friends slowly getting closer until they decided to marry.
They were happy together and when Charlie was drafted for World War 1 he encouraged her to find a way to keep busy. Esme went back to teaching, the schools allowing married female teachers during that time periord due to shortages.
They kept in touch through letters and one visit Charlie had gotten lucky to make home before being deployed again.
In 1919 when the soliders returned home the solider that met Esme was not her's. Pregnant Esme learned her husband was killed in action.
Esme moved to Wisconsin after that to her cousin's so she could get help with the baby. As a war widow she didn't have trouble finding a teaching job. She was starting to build her life again when another tradegy struck.
Esme gave birth to a baby girl she named Isabella. The baby contracted lung fever and two days later Esme was told the baby died.
Esme didn't want to live any more. Dr Carlisle Cullen, who found Esme in the morgue couldn't let her die.
Slowly Esme opened her heart again. She married again when she married Carlisle and took the others in as her own children.
Decades pass and Esme while still loving her first family loves this new one too.
Esme's heart cracks when they move to Forks and sees the chief of police home schooled daughter is what she always believed her daughter would look like growing up.
Esme's heart shatters when Carlisle introduces her to the Chief of police and she sees her dead solider.
Now let's rewind.
During world War 1 after his short visit with his wife Charlie Swan returned to the front fighting in Europe. It was here that a vampire took advantage of the chaos and drank from several soilders. The chaos is also how Charlie escaped with only a bite. For three days Charlie laid on the battlefield with fallen soldiers in agonizing pain while the venom worked his way through his system. He woke p thirsty, so thirsty.
The battlefield was barren but he needed to drink. Confused and lost, Charlie caught sight of a smell and ran towards it. His teeth sank into flesh, and finally he could drink.
As Charlie became more clear headed he stared terrified over the carcass. He stood over a deer, two holes in it's body with small amounts of drying blood. Immediately Charlie wanted to return home.
Charlie made his way across Europe to get back home. At one point he found himself in Ireland where he met Siobhan and her coven. Siobhan gave Charlie a better understanding of what he was and officially informed him of the vegetarian lifestyle that silly Carlisle Cullen lived by.
Charlie took that information to heart. He already been feeding off animals as that's mainly what he's been coming across during his way back home. Old instincts from his hunting and fishing trips with his dad.
During his way back home Charlie also leanred he had an ability. Those who's powers worked on the mind barley worked on him. A mind reader could only get a glimpse of his emotions, if someone made you feel pain he feel a pinch.
Once back in America Charlie spent two months tracking down his wife. His heart broke when he learned of her suicide and it broke again when he found out the reason was because of a mix up at the hospital.
There were more than one newborns with lung fever at the hospital. Paperwork got mixed up. When the doctors told Esme her baby had died they were talking about a baby boy born the same day as their Isabella. Isabella survived her lung fever.
Charlie looked for his daughter, found her in an orphanage and stole her away. Charlie raised as best as he could for years. He wanted his daughter to live more than either of her parents could. It was during the 30s, on Bella's 18th birthday did they both agree to change her. The great depression at the time, Bella couldn't take being hungry anymore, she rather be thirsty.
Father and daughter roamed around settling in place to place from time to time. Charlie often took night jobs as an officer as that was what he was doing before being drafted, and Bella was "homeschooled" or in college taking mostly night classes depending if she wanted to learn something new or not.
This go around they settle in Forks, Charlie's home town though it wasn't called Forks until the 40s.
Charlie meets Carlisle.
"So you're the vampire I hear so much about," Charlie joked.
Charlie feels like something punched him in the gut when he meets Carlisle's wife and sees the mother of his child staring back at him. His mind instantly racing on how he's going to break this to Bella.
Carlisle is going through a bisexual panic in the background.
