Dear Guest: About your question, vampires do not have soul mates in which things just click when the first touch/meet/see each other ect. It's more like they just fall in love gradually.
1600s
Carlisle entered the small house feeling completely defeated. He idly wondered if all vampires were so unwilling to give their name, let alone consider his lifestyle. Bella looked at him over the top of her book.
"I'm pleased to see that you are still alive. I gather he wasn't too open to your idea." Bella said and Carlisle shook his head yes. "That is no big surprise." Bella put down her book. "I think it is time we part ways, Carlisle."
"What?" Carlisle responded, completely blindsided.
"There is nothing more I can teach you. It is time for you to move on. You should go spend some time with the Volturi. Aro will try to change you to his diet, but I'm confident that you'll resist his coercion. They have a very large library and I'm sure you'll be able to learn more about medicine and anatomy than you could by staying here." Carlisle didn't know how to respond to her.
"But I thought-"
"I told you from the start that this was only a temporary arrangement. You are a good man, but if you don't move forward you won't be able to meet your full potential. There will be plenty of vampires there so you won't be lonely."
"But, you won't be there." Carlisle said, genuinely sad at the prospect of no longer having her around. Bella gave him a warm smile.
"We do not love each other. If you stay here with me you'll never meet someone who you can love and be loved in return." Bella's voice was gentle and Carlisle knew she was telling the truth. "You should go and become an even greater man." Carlisle could only nod in response.
Bella gave him detailed directions before they parted ways with sad smiles.
