I am not going through the same situation right now, but I definately know how hard it is not to pick up the phone and call him.
My recomendation for that is to find a good friend (preferably guy but girl too) who will tell you that you can call them ANYTIME you have the urge to pick up and call the guy. I have had friends who have done that for me, and it was such a big help! Most of the time, all you need is SOMEONE or something to keep your mind off of it for those few minutes. And as time goes on, you won't need to do it nearly as often.
My other recomendation to get through this time, when you are thinking about it constantly... Whenever you're sitting around and can't stop thinking about it, go work out. My best friend did this after one of her break-ups and she got into the best shape EVER! The endorphins will raise your spirits, and looking even better will help you feel even better about yourself! That will make you more likely to be in the mood to go out and show yourself off and meet new people!
And actually, what Bobby said is a good idea too. My guy friends are often the BEST ones to turn to when I'm having guy problems because they will take me out and have fun. And if you're not in the mood to be hit on by random guys, going out with guys will almost always keep that from happening.
