Well, honey, let me break it down for you. Scrooge and Belle went their separate ways because Scrooge chose money over love like a fool. Belle had enough of his penny-pinching ways and decided to leave his miserly behind. So, in a nutshell, Scrooge lost a good woman because he couldn't get his priorities straight.
Belle
Yes Belle does marry and have a family of her own.
Belle
No one. Scrooge didn't have another woman in his life after Belle returned his ring. She later marries and has children.
Money, "the Golden idle" as Belle calls it
yes
Belle
Belle
When Ebeneezer Scrooge was young he was in love with a girl named Belle; but she left him because of his obsession for money.
In Charles Dicken's A Christmas Carol, Belle and Scrooge were engaged as a young couple. Later Belle breaks off their engagement because she feels Scrooge's growing greed is changing him. When the ghost of Christmas Past reveals Belle to Scrooge and a grown woman with a family he realizes what he has lost.
He isn't. Scrooge is so focused on business that he wants belle to wait until another time to discuss the matter, he was busy. This was the telling factor for Belle as to Scrooges commitment. Later we see Scrooge accompanied with the Ghost shouting at the vision of his past to go after Belle not to let her go. This of course is the past and it cannot be changed but it does highlight that Scrooge did love Belle he just lost focus on what was important
In Charles Dickens' "A Christmas Carol," Scrooge's fiancee was named Belle, not Martha. Belle ended their engagement because she saw that Scrooge's growing obsession with money was consuming him and changing him into someone she could no longer love. This event played a significant role in shaping Scrooge's character and his journey towards redemption.
