To love and be loved...

Why is it so hard to be loved by someone that you love? It's a well known fact love is a two way street.  But sometimes it's a dark, shitty, one-way alley for a long freaking time before it becomes a two way street. I mean, think about it.  Odds are if you love someone that doesn't reciprocate your affection; there is most likely (whether you know it or not) someone that loves you, whom you do not love.
Is love even the right word for it?  I know people in my life I can fairly say that I love, but I cannot stand to be around for long. The Greeks had it right when they had more than one word for "Love", I'm going to have to invent a few more words for love to add tot he English language.  Anyhow I spose that is love being defined as, care for another persons overall well being, is what it is when you "love" someone you can't stand.    What I refer to as love here, is really more of a being made whole by another person.  That completeness you feel when you're with someone that makes you feel a way no one else does.  How is it that feeling can be one way?! It's so crazy that someone can make you feel complete, content and happy, yet you not have the same effect on them, but rather you have that effect on someone else, that quite frankly you can't really stand to be around.  Life is so messed up in ways.  I wish to goodness I could have my emotions surgically removed some days. Today is one of them.
