If you keep listening to someone else’s version of what happened to you, you will never be able to heal your own version of what is happening within you still, because of what happened to you to them.
When people clarify a lot on why they were right, it is a clear sign of them knowing they were wrong but being egoistic enough to not admit it. So they keep justifying why the other person was wrong
Bonus (unrelated one):
When you are going through a tough time, it is still important to recognise the people who care for you. Not everyone is raging a battle against you.
