Friend?, Enemy? EX!

I can be your best friend, or your worst enemy. What I don't understand is why anyone would want one more enemy in the world. If I had a choice, I'd like to make more friends, well maybe not a friend, but someone that I don't mind dealing with. With that said, I can't put my mind around the idea of someone telling me he loves me (and I'm absolutely certain that he does) but insists on putting me thru agony. Please give me a break! It's been over two years since we've broken up, and you still have a problem with me??? Get over it! But if we can't be friends, I promise I'll lose no sleep.
