I think the idea of a fresh start is fallacious. It insinuates that both parties make a separation of past wrongs, when the truth is that the wrongs will be remembered and in many cases a lot of healing needs to happen before the relationship can have a sense of trust and reliability again. Which is normally earned through action and doing the work to heal. This work can make some relationships stronger in the long run, but the idea of a fresh start would be then more of a white washed form of emotional dishonesty on both parties parts.
