What if Kim was a healthy adult? She would maybe not have negative experiences projected onto the scenario and perhaps could easily switch to making plans by herself without her group with healthy boundaries. - This is bizarrely reading things into the original question. The question is, essentially, "if a group of your friends announce they're doing something fun and give a fairly thin excuse for not including you and nothing else, should perceive your relationship with these people weakened". There's "emotional reaction", it's a judgement. Kim judges where Kim's friends priorities are. The thing about this is, the only place emotions come is that most people with social bonds see things like doing activities together as a "good in itself". Even if someone isn't concerned with whether they go to a show, the person can see this group isn't too concerned with maintaining that particular bond. How a person reacts afterward isn't part the question, isn't part of my comment and seems like throwing your particular psychological baggage at the whole question.
