Making someone happy when your not

I thought our discussion on Tuesday was very interesting about single life.  The most interesting part about it to me is that one of the main purposes if being single is to find yourself and figure out who you are.  This is interesting to me because I never really thought about being single that way.  I have always seen being single as a kind of negative thing at least for me.  I have been in long term relationships since I started really dating.  Now looking back at those early relationships I realized that they didn't work so well because I was not happy with myself at all.  Currently I am in a three year relationship and we are very happy.  Thinking about the discussion in class I realized that since I know exactly who I am and I am happy with it, it is much easier to have a relationship with someone else.  Since I know myself it allows my boyfriend to know exactly who I am.  He knows everything about who I am and he is happy with it.  I do agree completely that you have to be happy with yourself and know yourself before you try to enter a relationship.
