I think the best advice would be to spend as much time with friends as possible. Spend time on other things you enjoy. If you like your contour, wash it more often, wax it..etc. Just do something to take your mind of her. Time is the only thing that will heal.
Meeting someone else will be difficult if you're a little quiet but then again if you're that kind of personality, then you're looking for something meaningful which can also take time. Sometimes you meet people in the craziest places when you dont expect it at all.
Just hang in there!
