If an infatuation was having a negative impact on your life, would it be best to avoid the person?

You are infatuated with a person who is making you see the good things in your life that you gained whilst they were not there, in a negative way. Sending your life completely out of wack (like making you forget your priorities which are the good things, losing sleep etc) even making you see yourself as a bad person towards the good things. And this happens every time the person enters your life.
