Why do I love you?

My life feels like a country song these days. There's a song out there I can not think of the name...about wanting someone when you just can not seem to make it work out. Loving them or wanting them even though you know you shouldn't. That is where I am at these days. There is someone that I love more than I have ever loved anyone, but we just can't seem to make things work out. We love each other, but we hate each other. We value each other's opinion, but we don't want to say one is right and one is wrong, even though we do not agree on most subjects. We continue to support each other and look out for each other but living together is out of the question. I trust him with my child but I would never trust him with my heart again. He hurt me so bad in the past I didn't think I would ever get over it. I have. But I still remember. We both have said awful things to each other in anger, and then are quick to apologize. It's confusing. And yet we are attracted to each other again and again. He's actually the only person that I think I have ever really loved, maybe the only person I will ever really love. I don't know.
Or another song runs through my mind...I hate everything about you...you hate everything about me...why do I love you?
Some things I just can not seem to figure out.
Maybe it's just better to not to try to figure it out.
