Some of my clients are caught between a rock and an abandoning place. Because they long for someone those feelings build up an imaginary relationship. Longing reinforces longing. It does not change the reality of a one-sided relationship. Be kind to yourself and feel good that you want to love deeply but continue to trick yourself by believing that desire will change a person that you love from afar. Either the person you have a crush on is responding with respectful words and behaviors otherwise they merely like that you desire them.
