Did you ask this question before, or was the asker someone else? I'm glad you picked Cogito's answer because I agree with her. It will be embarrassing to you and to your beloved when the crush is over, especially if people you know find out.
I suggest that you write the story for your own enjoyment. In a decade or so, you might want to relive the feeling of that crush when writing another novel, not so personal to your life, and there it will be for you to re-examine. Or you might marry your crush, and you'll have something to read to him after "the night of nights". Or you might have a daughter, and, one day, she will undergo the throes of a crush. It will be nice for both of you to understand that "Mom / I had been there."
