I am sorry to hear of the pain you are going through right now. If things aren't in a good place then maybe you taking this time truly apart could be beneficial for both of you to have the time to sort things out for yourself.
It is not easy at all to have her leave, but it sounds like things have gotten to this point for a reason. You both hold the cards and try and communicate your feelings in a way that you can feel herd and understood.
It sounds to me like the dynamic right now is not working so a break might be the way to go...give yourself and her that time and things will play out as they are supposed to. It's not about whom has apologized more or when..right now the communication has broken down so time for a break.
