If they trusted the person then they wouldn't mind giving the person their space, because they would trust the person to stay with them. Should that person leave anyway, then their heart simply wasn't in the relationship to start with... something unavoidable and uncontrollable even if you were to do everything "right."
Clinginess has a nasty habit of becoming a self-fulfilling prophecy. They fear the person will leave so they cling tighter to the person -- so tight they start to smother the person emotionally. This forces the one they love to have to make a decision, either live in misery or leave. Naturally, they leave.
