The best thing to do would be to just stay out of each others way for a while. People need time to heal after a relationship and that cannot be done when your in the same person's company all the time. Give it a few months then when you think that you are completely 100% over her you can try and be friends. I for instance are still friends with all my exes, but it took time to get to that point and it is not always easy. In some cases old feelings start coming back, and makes the situation tricky, but as soon as these feelings come back just try thinking of what it was that went wrong and that you broke up for a reason.

Noooooo not a good idea at all. Just imagine if she suddenly gets another guy and you run into them at a random event and she decides to introduce you to this new guy because you're "friends" how would you HONESTLY feel about that?
