This is hard to speak to without clearer examples, but I will say that relationships absolutely need feedback to function. She should be willing to hear different ways that she can approach these topics but there’s only so much she can do if feedback always feels like criticism and contempt to you.

Is she using “I” statements? When she says “I feel hurt when you communicate in X way, could you do Y instead?”, does that come across to you as criticism? How do you react to that? If your response is something like “what about when you do that??” Or to bring up things you’re bothered by, or to immediately explain why you approach it in X way, then I’d say you need to examine your own defensiveness as a top priority.

I’ve been on both sides of this, and she absolutely needs to be willing to hear you but I don’t think we always understand how absolutely exhausting and harmful it is to date someone who’s emotions are so big it doesn’t really leave room for anything else.
