I feel you dude cause trust me, I'm on a break with my girlfriend right now with no contact and there's nothing I want more than to text her or shoot her an email saying the same thing. But in all honesty there is NO way to avoid the awkwardness that will come when you guys see each other again. My ex texted me 2 nights ago and then IMd me the next day to explain herself and it was just awkward... this is someone who I was more comfortable with than anyone EVER and it was just plain awkward... no two ways around it. So while I feel for you and I want you to text her, logic says don't do it. Just take comfort in the fact that she's definitely thinking of you and you know she can't simply walk away... we all need closure, its human nature.
Give her time to stew and to miss you... if she gets a text from you, even if it is something as innocent as "dont feel any pressure," it shows her that you're the one stewing, and you don't want that. Remember, we want what we can't have, and if she thinks that you're doing well without her it will strengthen your position. It sucks to have to play these games and overanalyze everything like this, but trust me, she's just as insecure about this as you are, if not more.
