Well, the same thing happens with any other relationship that you might have friendship, your family life. You don't want to share every detail about you, but you also want to make sure that you're not violating somebody else's emotional boundary, too. So if you want to share something that's very emotional and personal to yourself, you must ask permission to share with someone so that it doesn't cross their emotional boundary. That's the appropriate thing to do
This is just an example, but if they were to say, hey, something on an emotional level that I can't really handle, it's really tough to kind of stop them, especially when they're in the middle of feeling that emotion and really feeling how raw it is. So I feel like this is something to be discussed long before anything like that would happen. Probably the sooner the better, in a calm conversation to express these emotional boundaries
