Well, she is communicating loud and clear how you have not been setting boundaries, but rather trying to control her. You did well in acknowledging how she felt.
If it were me, I would do the clarification on the R first - I assume that's "I won't have any relationship with you while you are in EA?" - correct? After that clarification, I would not push the MBR immediately.
What usually worked for me was to set the boundary during a clear calm moment, and in advance like , "I will sleep in my own bed in my own room, and I will start next Saturday" - or something like that. Be prepared for the blowup, and practice say, "I'm sorry you feel that way" lots and lots.
