What kind of peace would you feel if the person you love the most cheats on you? I would feel anger, resentment, disgust, and indifference to that person.
If we are in a committed relation, I would never forgive my Twin Flame if he cheated on me. That would be the end of our physical relationship because cheating is unethical, unfair and gross.
Twin Flame or not, being unfaithful is disgusting.
Dude, rethink about all this, don’t let someone use you because they say that you are Twin Flames.
I think this is an issue where people label their relationships as “Twin Flames” just because it is convenient.
Being a Twin Flame does not mean that you should accept narcissists, emotional vampires, cheaters, liars, and all sorts to take advantage of you!
You deserve to be treated by honor, and respect.
If you are a Twin Flame and living an authentic Twin Flame journey, you would not be asking this question because that is not what the Twin Flame journey is all about.
You deserve better than what you are accepting from your partner.

Stay Blessed.
