What's that old saying? "Fool me once shame on you, fool me twice.......", so I say "No", all is not forgiven.
These Cs are like the abuser in an abusive relationship where two people truly love each other. We are the abused.
They tell us they love us, they have to do better, that they are sorry, they change for awhile, and we are hooked again, because they have turned it around in the past, and WE TRULY WANT TO BELIEVE IT.
They then fall into that same pattern of behavior, and we are kicking ourselves again for having bought it, and somehow feel worse than we did before.
This team needs to be shaken to it's core, and I mean that literally and figuratively.
