What is Love

What is Love? The age old question that no-one seems to have the same answer to. At the end of every relationship, I am left with this question. And the reason I knew this one wasn't it was my gut reactions in a couple situations. So the way I see it, you can follow your head or your heart or your gut. I've decided the gut is the best. But it's so hard knowing that I could drive two blocks, walk in his door, and all this agony would be over.
I'm sitting on his couch, holding my empty tea cup........frozen. I can't move. I should just head for the door. But part of me wants him to talk me out of it. And he tries, but I've spoken this truth to too many people to be able to explain the opposite now.
