It's over. Stop pining for the past, find someone new, and get on with your own life.
Most men learn early in life that once women break off their relationships, they are likely to break it off again. "Once bitten, twice shy", as the saying goes. So when you do find a new man, don't drive him away. Don't try to change him, and don't even try to give him an ultimatum - telling him "It's my way or the highway" risks him choosing the "highway" option at least half of the time.
Let him go. It's over.
