The last key ingredient to a relationship

both people have to want to be in it. without that, you're pretty much fxcked.

Differences between Need and Want

You could wake up one morning and realize that you're not dependant on the loved one who is been irritating you. And depending on what your life has looked like before that point, you could yell, "I don't need you!" and chase that person out of your life.

But that descision could lead to regret if you realize that you really want (but don't need) that person in your life. You could make yourself miserable. Be forewarned.
