Fool me twice, shame on me. Fool me the third, fourth, fifth, sixth, seventh, (etc., etc.) time, please, for the love of all that is good in the world,GTFO.
Everybody makes mistakes, and everybody deserves forgiveness.
We trick ourselves into believing that things are going to change, but when you look at the repeated behavior pattern and consistent relationship issues they cause, it’s not logical to believe that would be the case.
When it comes down to real action, to making real changes in our lives, we hem and haw and make excuses for the very disrespectful, dishonest, and just overall sheisty ass behavior that makes us simultaneously burn up with anger and die a little inside.
Don’t give that person the satisfaction.
