I just believe people have limits. Mine was reached at the suspected new relationship she rebounded to from her A ending.
I'm just going to be honest here, I think you got scared she was starting a new relationship and wanted to shock her into waking up by realizing she can lose you. You reached your limit on something she MIGHT have done? A suspected rebound? Sorry, just not sure I buy it. We need to act from a logical stance and remove emotions from our decisions and I'm not sure that's what you did. If D is what you want then so be it, that is your right. Evetyone had the right to decide how to live their life but you have to accept the consequences of your actions just as she does.
If your done your done, that is fine but I would make sure that's what it is. Ask yourself this question, would someone who's done care how the other is reacting to being served?
Accept what is, let go of what was, and have faith in what will be
