I think it's possible that she is overly sensitive because the situation is nothing you can change. This may be true in that she could feel slightly guilty about the situation and may feel that others are judging her. There is a second possibility. Different people have very different ways of resolving conflict or disclosing to others. She may just be a very private person and you are a very social person. Private people tend to feel very insulted when details about them are shared in a social setting. You may be a different kind of person and you are not threatened by such exchanges. Regardless of the reasons it is obvious that she sees sharing details about your marriage as an invasion of privacy. So from this point forward just use careful judgment as to what is and isn't off limits. You didn't do anything wrong. The two of you just have very different ways of finding acceptance or common interests in others. As far as what you disclose, that also is a personal decision. This can be resolved and is a common issue in relationships
Was i being to sensitive by asking her before the end of the call " are you going to divorce me over this?, are we still on good terms".
Her response was " no im not divorcing you, and yes we are still on good terms and i love you".
