A few questions...

Why can't my ex and I let go? Why do we still talk on the telephone multiple times a week? Why do we continue to put up with each other's shit? Why aren't our respective current significant others higher on our 'priority totem poles'? Why do we still say, 'I love you' at least once every other week? Why are we meticulously planning our plans to celebrate my birthday this weekend? Why, after 18 months, are we so into each other? Why did we talk on the phone until 2am tonite? Why are we not together?
