time is the healer. Don't lose contact though. Best bet would be to give it a week, organise a neutral place to meet (i.e. a resturant you've never been to), so no memorys of yester year and start a fresh.

Make sure you listen to what she has to say and discuss in depth how you're feeling to each other, your likes and dislikes. Give each other a little bit of space to think afterwards. I know what you mean about the sick feeling, it certainly doesn't help the thinking. If you love each other then the space will only make things harder to stay apart and will pull you back together. Just don't rush it and don't pressure her into seeing you. do it in time it takes for her to want to do it.

Best of luck mate and hope it all works out 4 ya.
