I understand myself pretty well, I think... I just don't feel that sense of completeness that other people talk about, especially with regard to relationships. Someone recently told me that they if they never find love or get married it won't bother them. They can still have a happy and fulfilling life. But not me. That scenario sounds really awful to me.
I am trying to view my incompleteness positively now though. Picture a glass that is completely full of water: the water symbolizes love, or knowledge, etc. If someone else wanted to contribute to my glass and I was already full/complete there would be nowhere for their contribution to go. I would rather have some extra room, so that I am receptive, and I want to maintain that state throughout my entire life no matter if I find love or not. So I no longer expect a significant other to complete me or to fill my glass, but still, if I go through the rest of my life without a significant other wanting to at least contribute to my glass *and have me contribute to his* I will be very sad.
I hope that makes sense...
