I think the MLCer feel they are being mastermind manipulators, my W recalled her well thought out and calculated plan to leave me and kids. Once they let go and jump into fantasy mode and run, they don’t realize how poor their further attempts are - like a child thinking they are getting away with something, it is written all over them. A giant mind game indeed.
Feelings are fleeting. Be better, not bitter. Love the person, forgive the sin.
