I think it might help ground you to look at the facts rather than fantasize about what may be. Ask yourself some questions... How long has it been since you broke up? Has he made any effort to get back together? How likely is it that he has moved on with his life? How successful have your attempts to reunite with him been? Is it possible that your pursual scares him or might be illegal? Who tells you and shows you he loves you in your present life? Who craves a relationship with you and your attention? Who would notice if you decided to run away and join a convent? Who comforts you when you are in distress?

You get the idea. Maybe you can find some things about your current partner that meet your needs in the way no one else has before. If you're feeling too restless, maybe you can do some traveling.

For what it's worth, I'm also trying to get over my ex. We were together for 12 years and I thought we were soulmates. It's been 9 months and I still have the urge to inject myself in his life every day.
