<human>: Can you condense the text into a few key points?

I (28/m) broke up with my girlfriend (29/f) of a year, about three months ago. It's been rocky for me, to say the least. 

To put the long story as short as possible, I did the breaking up, then realized it was a mistake, and didn't handle it well. She wanted to be friends really quickly, and I didn't handle that transition. Our main contact has been through email, and I keep putting my foot in my mouth. In October, I asked if she'd consider getting back together, she told me to fuck off (in so many words), and I agreed I hadn't been tactful, and suggested a month of radio silence.

After that month, she reached out a few times, just genially, and I responded in kind. Things were very distant and curt, but pleasant. The other week, I finally unfriended her on facebook, because I was constantly tongueing the wound and looking at her page. She noticed and considered that hurtful, and reached out saying so in email. I tried to explain I was just trying to distance myself from her on social media so I could move on, and that it was about me, not her.

Cut to this week. I send a quick email checking in, she responds saying she's fine, and that she has an old thermos of mine and to let her know if I want it back. I decide that maybe this is an opportunity to show I'm not trying to just sever ties with her and suggest coffee. She comes back with this whole "you hurt me with the facebook thing, I thought you wanted to distance yourself. No thanks; I'm concentrating on the friendships and relationships I already have." Subtext: fuck off.

So I want to say "well dude, email has been doing me *no* favors; I do miss you as a friend, I'd like to just sit and chat, because I keep putting my foot in my mouth here in cyberspace." 

It's frustrating. I feel like every online interaction just stirs the pot, and having a talk as friends over coffee would be a step in the right direction, but expressing that may only further stir the pot.
<bot>: I feel like I've nuked our chances of friendship, want to explain myself, but feel like that would just be like blowing on the ashes.
