<human>: Can you condense the text into a few key points?

Almost 4 weeks ago, my ex broke up with me a few afters after I flew home from vacationing with each other. It was really unexpected and quite ugly, and she immediately cut off all contact with me. It hurt so badly, and while the pain still comes and goes in waves, I do feel like I have improved overall. Being about 1200 miles apart from each other probably helped in this regard, and I have installed web blockers to prevent me from looking at her facebook/tumblr/instagram, etc.

However, on Sunday I am flying out to a summer music festival (we are both classical musicians). We both applied and auditioned for this program several months ago and were accepted. I have decided that I do want to follow through with this festival, as I have been trying to get in for about 4 years now and I think it will be a good move for my career.

I am afraid, though, that this will negatively impact the progress I've made towards healing/moving past her. To make matters worse, we will be in an isolated woodsy/coastal New England town (excited for the scenery, but not so much the inevitable proximity to her). Seeing her every day will be hard, and I was just wondering if there was any advice that you all could send my way in regards to seeing her, how to act around her, whether or not I should avoid her, etc.
<bot>: Ex-GF broke up with me, then we spent 4 weeks apart. Now I will have to spend 5 weeks with her very soon and don't know what to do.
