>>2 is spot on. You can't be just friends with her, because you still have feelings for her. I think you should explain this to her, so that she understands it. You will be able to be friends with her only when you stop loving her.

Also, I would stop meeting her too much. You can also explain that to her. You are in pain when you meet her, so for the moment it would be better if you reduce exposure. This does not mean that you should not say hi or be rude or ignore her. Just don't spend time with her. That's why it's better to explain these things to her, otherwise she may misinterpret things. Once/if you get over your feelings, and you give up on her, you may be able to spend more time with her.

>remember good things fall apart so great things can come together.

Very rightly so. I think it's great you could experience such feelings. Hopefully you will soon be able to share them with someone able to retribute them to you.
