Trust me if she finds him again it will be because she is looking or he is really stuck on her.
I don't know if it was wrong or right but I will say that I don't think it will change much. difficult child's find a way to be difficult child's no matter what we say or do. If she wants that relationship it wont matter what you said, did, or blocked she will find it. He wont change he will just move on to another target.
On the other hand did it make you feel better? Give you some hope that he might go away and she might not go searching for him? Then I would say it had a positive effect for you.
