How you react and cope with someone who has hurt you deeply is a personal decision. I once had an ex that cheated on me (this is the first occasion that comes to my mind right now). getting betrayed and lied to by someone you love is not a good feeling. However, what he did was a reflection of him, meaning, he could not stay loyal becuase he is an insecure man who was trying to find validation through other people. Moreover. cheating was his decision, and I could not do anything more than remove myself from the situation. In the end, I decided to forgive him and not hold a grudge, but I will never forget it. I am now more careful who I let myself commit to, and I got a good glow-up too;). I have no regrets, I only gained new knowledge!
