He found a new girl and got married.
He forgot all about the singer.
He hasn't moved on, he is still in love with the singer.

Win her loved one back.
Wait for her loved one to remember their love and be together again.

Sad and wants to cry.
Happy and optimistic she is going to win her loved one back.
