v1, I agree with Glimmerman that she knows you're upset and she'll keep her distance but eventually she'll want to talk about it. However, I think you do need to go dark on her, even if she tries to contact you, you should ignore it. Now that you let her know (and I see nothing wrong with it) how you feel about it she needs to simmer in her guilt (if there is any). She will feel guilty and to ease her guilt and only to ease her guilt she will contact you but like I said you will be unavailable (not a peep) as she can't know (nor does she deserve to) how you're feeling and if you're good/not-good/ok etc. It's her time to mind read and analyze stuff. If she contacts you multiple times then only then you should respond but keep it generic (no emotions).
At least that's what I would do...
Hang in there! you've done the hardest thing most of us will ever do and you made it out alive. Things will start getting better for you from now on- just give it time.
