How is your relationship with your ex?

I understand her position. For her, this is a zone of discomfort, and I am ready to accept it. But you know, I don’t want to lose a person who has been by my side for so many years and has actually become an important part of my life.Is there a solution here? I don’t know yet. But now this question is constantly spinning in my head. And what do you think, is it possible to have a sincere friendship between exes?
