Are the novels the cause?

Are the novels the cause?

I had a friend who had met a pretty girl, she was charming, with hazel eyes, brown hair, she wore beautiful dresses, it looks like they were sewn specially for her, my friend was starting to find her perfect , As she was well educated and always had a smile on her beautiful face, covered with spots of redness that went wonderfully well.
She read the novels, she read much at a point where she fell asleep and the book opened at her side.
My friend became more and more attached to her; One day he opened his heart and confessed to her that he was in love with her, she replied that she also loved him, he was delighted to hear the word "in love".
He spent a good time with her, after a few months with her company he took the decision this time to ask for her hand, "honey, we spent moments together and now I want to know if you really love me?" Staring at him and replying "my darling of course I love you, you're the only love I have", "So I ask you to marry me!" ask her. "Okay," she replied, he was mad with joy.
He told her that this week I will start the administrative process. She replied that it would take a little time.
Months pass and whenever he talks to her about marriage she turns away the discussion and begins to tell him a romantic story,
he came home and started telling me his story, I immediately figure out That she was living in an imaginary world based on novels.
I told him my opinion , he looked at me with a strange look and said "are you sure? "
I was stuff, I didn't know what to say
According to you readers , is it possible that she is frozen in an imaginary world?
And if yes, what should he do to get her out of this abyss?
Thank you for your help dear readers.
