I know how you feel, and it does hurt. I think what you have to remember now is that it can't get any worse. This was probably the last thing you wanted to see, and you saw it. Does it suck? YES. It is absolutely painful and cuts you deep. The good news... you can only go up from here. You have pretty much hit rock bottom now, so as bad as the storm was, the center of it has passed. Clearer days will be ahead if you can be proactive enough to let this go and focus on your own life. This is the progression of life, people breaking up and getting with other people. It was bound to happen, now learn to accept that and start making yourself happy. Who is to say, that she doesn't walk into a movie theater a few months from now and you are with your new girlfriend... I am sure that would sting her a bit too. No one wants to see that, but it is reality.
