To what extent does our need for people really depend on their qualities and nature? Do we need certain people or just their presence? In other words do we love relationships or people?

It just happens that we meet some people and there are billions of people we'll never meet. So we just spend time with those we have met. If there is an attractive force acquintance turns into something more: friendship, love.. But in the end anything that really counts is this force acquintance/chemistry, isn't it? Of course many of us have the list of important qualities we don't want to see in people beside us. If to look just at the list with shortcomings we all understand that the longer the person is beside us the more we are getting used to his/her presence and his/her shortcomings. And in many cases we just can't let go even if nobody gets anything good from this relationships anymore. We don't want to change anything - we are so damn afraid of changes. 

People or relationships? Certain attitude to us or presence of the most important (for us) qualities? Do many of us deserve both?
