Go no contact. Don't visit her FB, her other social networking sites, don't text her, call her, IM her. Nothing. Regardless of who broke up with who, it has ended. The last thing you need right now is to be reminded of her. Trust me, the more you dwell on her, the longer you're prolonging the agony.
Your priority is to yourself. Go to the gym, take up a new hobby, go out with friends. Take your time to heal. Eventually you'll move on. There's no definite time on how long you're going to heal. But if you try hard to focus on yourself instead of your previous relationship, you'll get there, buddy.
