Sick and tired of holding onto false hope, how do I ask for closure?

It's been exactly 1 month today since my ex dumped me for unknown reasons. I was completely comfortable with her and thought everything was going fine and out of nowhere she breaks my heart. I accept it, agree on the offer of friendship, breakdown 2 days later and pretty much beg for her to take me back, I know now this was a mistake.

I've been no contact for 2 weeks, hoping she'll come around, but now she has asked my best mate out for coffee 1 on 1, I was expecting her to ask someone out to coffee since I had been no contact, but I definately didn't expect it to be my best friend. It's possible that she's playing games with me as last week I went to uni orienation with her best friend and we were hanging around together all week, but the difference is, her best friend has a boyfriend and I would never look at her in a romantic way, my best friend and my ex are single. ALthough I doubr she would be playing games, because what does she have to gain, she dumped me?

I saw her for the first time in a few weeks yesterday and gave her the cold shoulder. But when I heard that she asked my mate out for coffee it really upset me, I NEED closure, I NEED to know that I have no chance in getting back together with her, I haven't talked to her in a few weeks, I deleted her off facebook and have been blatently ignoring and I think she knows this, how do I talk to her? what do I say :O
