How do I manage my emotions regarding people who are no longer in my life?
Not long ago, my first boyfriend broke up with me, along with two friends who decided to end our friendship. They all had their reasons;
the relationship with him wasn't healthy, And I have recently learned from third parties that since the breakup with me, he has tried to harm himself more than one time.
I had told one of my friends something personal about the other, about a crush of hers that I thought my other friend knew about, and since I didn't specify the age of one of the boy involved, they thought the worst-
Currently, besides feeling upset about how unstable he is, I discovered that the friend who introduced us had hidden the fact that she developed a crush on my then-boyfriend once we started the relationship, Due to her behavior at that time, I experienced many jealous and insecure moments during the first year of our relationship, and many things could have been avoided if she had been honest from the beginning instead of She told me that she saw him as a brother and that she simply liked a boy who had confessed his feelings to her years ago (which in fact, my ex did).
They're no longer in my life. I know I should probably ignore them and not receive any more updates since they're not my problem, but discovering that only two years later makes me feel sick, plus, I am an emotionally hypersensitive autistic person, I'm already in therapy.
What tools could I implement to lessen the impact of the situation and my thoughts on me?
What could I do to avoid feeling guilty about the behaviors and decisions of people who are no longer in my life?
What things, besides what I don't want in a future relationship, can I learn from all this?
