Ahh, name calling. Leave a short email saying you respect her decision, but you see your mistake. Leave a short and concise apology describing what you are apologizing for. Put "I know I probably made her feel like she's defective or broken," that in somewhere. And say if she wants to talk about it, you will be there. And leave the end with a simple "Love, " just so that it is clear you want to be back together.

And then leave it alone and cross your fingers.

Pushing for a solution or being blunt about the situation should be okay, but:

if she's in a pissy mood it's not okay to take it out on me, and being an asshole is never okay.

translate that into: "From the way you are treating me, obviously something is wrong. What happened?" Hash out the "taking it out on you" part immediately after resolving the first issue. It is just alot emotionally to deal with both issues at once. You deserve to be treated well too, but emotionally multitasking isn't easy for many people to do, especially when they are emotionally overwhelmed enough to be taking it out on others, i.e. loss of control. It's not personal towards you, and in a twisted way, it is a compliment that she trusts her emotions with you and not others. Not that that what she did is healthy or respectful...but when she's out of control, it helps if you are in control.

I know I probably made her feel like she's defective or broken.

No one thinks they are perfect, so being called out on a flaw is going to happen and should be expected.

Fights suck because it brings up everything you both are holding back and it is really hard for either party to step back and be reasonable. Criticizing someone is hard for the listener, so be as blunt as you want to be, but subtract your emotions from it when you deliver it, if you can---because, well, I don't deal with projected emotions well. And give reasons if the reasons aren't obvious.

blah, blah. I gotta stop typing. I wish you luck.
