Romantic story?

Rating: 4/10 (10 August 2017)

I was absorbed in watching by the first half. Noah, starring as Ryan Gosling, and Allie, starring as Rachel McAdams's love scenes are very romantic. Their separation is so pitiful and makes me be anxious about what would happen after this.
Allie gets a new boyfriend after she separates from Noah. This guy is very good man and they become engaged to each other. But Allie sees Noah again by chance. They still love each other, so Allie starts wavering between two men. I got annoyed at her indecisive attitude. Moreover, she takes it out on Noah and her mother. It is James, her fiancé, that the sorriest person.
At the end, Allie and Noah get married but she has dementia. She cannot remember Noah and her children. I think there was no need for making she have dementia.
