Hi Adam,
Someone to get angry at a confession of your feelings about them is a little over the top. They are just feelings.
She is the one making things complicated with her anger.
I would leave her alone. Don’t actively start to communicate with her anymore. Respond gently, yes, but don’t start anything.
I also have a feeling that one day she might try to revisit you.
Buddhist Lesson # 2: Let it go ~ for you by not communicating with her. See (and accept!) what happens.
I think you deserve someone better, IMO.
Best,
Inky
