Hello Naia
We’ve all done things that we are not proud of. The question is what we learn from those mistakes. It sounds to me like you are a sensitive person. I also get the impression that you felt extremely disappointed that your friend resented your happiness. This made you very unhappy, but because of who she is (assertive) you didn’t know how to distance yourself from her. I have the feeling you did what you did because you wanted to force an end to the relationship. This is of course not the right way to do it, but at the time you didn’t see any other way. So the situation is also a very good learning experience for you in the art of letting go (often a VERY hard thing to do. You’re certainly not the only one with that issue. Most of us have experienced the same thing in one form or another). If you can learn from it, then you’ll have a much easier time the next time you are in a similar situation. It’s good to be there for other people. It’s great to be there for ourselves.
