Are you aware of the concept of the highly sensitive person?

As a child, I cried often. My parents were not understanding of it at all. They shamed me. They said that I was a baby, as did many peers. I was teased often for crying. None of this made me stop crying, it just made me feel rejected and unworthy. Based on that experience, I think that nonjudgmental acceptance, not silence, not criticism, and not disdain, is the way to help a person stop crying.

In the event you described in your original post, you said that you cried for four hours because you thought that he hated you. Thus, it sounds like it wasn't the misunderstanding that caused the four hours of tears, it was the thought that he hated you.

From your other posts, I remember that you have experienced abandonment and have suffered a lot because of it. Any type of felt rejection, then, can perhaps trigger your feelings of abandonment, and perhaps lead to a lot of crying.

I expect that if your cousin's husband were clearly and nonjudgmentally accepting of you as a person, rather than shaking his head at you and being silent, it would be easier for you to manage the emotional impact of misunderstandings. How long do you think you would have cried if you knew in your heart that he accepted without judging you?
