There may be a couple of ways to go with this.
The first and most optimistic stance to take is that you have already experienced the moment of realization.
Now you can let go or move forward, and you may be quite ready to accept the inevitable change that must come on its heels.
You are putting things into perspective and not crying over spilt-milk, and are confident in your assertion of no more tears and self-pity.
Conversely, you may be using this moment of truth as a means of denying or ignoring the warning signs, or are overly rational to keep from losing it.
If you don’t want a recurrence of the pain or sorrow, take steps to move to the next level of actually letting go.
It’s time to accept, forgive and then raise your own standards.
Then move on and mean it.
