Find a way to build up yourself esteem. That was the only way I found out I wasn't in love with the guy who ripped my heart apart, I was really in love with the feeling he gave me when (very few occasions) he made me feel important and wanted. You are important and wonderful by yourself you don't need him. It took me a year to be ready for a relationship with out being afraid I would put myself back into that. Its hard to believe in yourself but definitely worth it.
