What to do if your obsessed with your ex bf?

tell them to get over it! Agree with above and add that if you are being unduly pestered and bothered, you can seek legal counsel and have a court ordered 'restraining order' issue against that person.

The ex probably believes that the relationship is salvageable, and for that reason refuses to accept life as it is. This is unfortunate for both people as it is now time for everyone to get on with their individual lives and start anew with fresh beginnings again.
