The advice I've received and seen passed around on the boards would be not to initiate contact or try and fix your mistake. I believe it's also covered in the DR book but can't recall 100%.
When she does initiate contact I don't think you should force her to apologize first. If you want it might be a good time to establish some boundaries that hitting and name calling are unacceptable.
You've gotta stop trying to talk over her, remember she does not give a s*** about what you have to say or how you feel, you are there only to listen and validate.
