When a young person develops a teen crush, it can be very overwhelming, and it might be the only thing they appear to be thinking about. In their mind, they may be planning a fictional future with this other person and anyone that tries to dismiss this plan may become a target of their dislike. Teen crushes are often combined with hormones, so what may be reasonable to them is often unrealistic for parents. Their love can intoxicate them to the point that this is all they think about and when things do not go to plan, it becomes painful.
