I can't understand firsthand what you are experiencing, but it sounds really hard and I can imagine it would be very hurtful to feel she didn't understand what you had told her about your trauma. Would you feel comfortable telling her how it made you feel?

I don't want to speculate too much, but it seems that you are catastrophizing a bit about the relationship not being genuine anymore. Like if the dynamic has changed that the relationship is totally gone. I don't say that to minimize your experience, it's just something I've done before myself and so I wanted to bring it up just in case it is helpful.

I am editing to add that I may have misunderstood and perhaps you meant you feel the relationship is not genuine. I read it as you thought you really did not have one anymore. Sorry that I may misinterpreted and my response may not be useful.
