Someone's burying my luck

So basically we got back together for a weeks and one night I woke her up at 2 a.m. and told her I didn't think we were right for eachother. I know in my heart it was right. it was, by far, the most mature decision I've ever made. I've been doing okay I guess but I definetly miss her. I have seen her a few times(no sex) but in my head I always wonder what is the point. Just recently I went to her house to drop off the last of her things and got on her computer and found that she made a profile for match.com. She's so about moving on and getting married it scares me. It is selfish but I don't want to see her happy. She works all the time and should end up lonely and left without. Obviously that is not the case. I feel kind of dazed as of right now, I haven't cried or anything 'm just a little taken aback by her moving forward so quickly. She's beautiful and i know she'll get scooped up soon. It won't be hard for me to move on but i thought it would be for her. i initiated all of this. SILY
