Why would you want to stay in an unhealthy relationship? Are you trying to avoid the pain of the grieving process? Waiting for him to change will just prolong the pain. And then you will still have to go through the grieving process. If you move onto your next relationship without going through the grieving process, you bring old baggage into your new relationship and that won't work. Change and growth are part of the recovery process and they are both painful to go through, the only way out is through. We can help you through but we cannot help you avoid. It will keep coming at you until you face this.
