Your ex is dating someone else
If you find yourself stewing in anger over something that someone else did or didn’t do, try to pull back and remember the good qualities you saw in them when you first met, and recognize that we all have flaws and we all make mistakes. Many other factors and circumstances, such as timing, incompatible values, or the choices we make, play a significant role in whether a relationship can thrive.
But moving on from a relationship that isn’t working isn’t always about ending the love you feel.
When someone betrays the trust you gave, it is painful.
But letting what someone else did limit your ability to move forward means they still exert control over your life.
For better or worse, it is in our nature as human beings to operate from our own self-beneficial perspective and the impact of our actions on others is often a secondary consideration.Politely let your ex know you need your space and would prefer not to be in contact for the time being.(Don't ghost them.) If you must remain in contact because of children or other shared obligations, know that there is a distinct difference between being friendly and being friends.It doesn’t really matter what the circumstances were, or who was right and who was wrong. Keeping an ex in your life is not by itself a sign of maturity; knowing how to take care of yourself and your emotional well-being is.
