I know it hurts. I know u didn't deserve it either. My advice is that u pick up the pieces and move on with your life. Get your hair done, your nails done. Throw on that killer outfit that acccents ur curves and get out. The best way to get over one is with a new one. It always worked for me.
Sorry to here that, but i have been down that road myself, and yes it is very hard and each minute that goes by seems a lifetime but you need to fucus on yourself and to try and move foreward as hard as it sounds, but time will heel so hang in there and good luck.
