Some people have what is known as an “anxious attachment orientation”, which means that they hold on extra tight to the person they are attached to. They are likely to want to constantly be in contact with their love-interest, want to know exactly where they are all the time, and react poorly when their date displays their independence.
While it may seem that they are behaving this way because of their loving nature, in reality it is because they have an underlying nervousness about relationships, spurred on by an unconscious fear of abandonment. Sadly, this controlling behavior can push away the very person you are so desperate to keep close. If you have this tendency, you need to make a strong effort to stay cool and not smother your date.
