I think your situation is much better than many others here. Reminds me of how my W and I were about two years ago. If I had known what to do then, I probably could have avoided the brutal events since.
I'd say if she wants to talk about the past, listen and validate. Don't comment much, and definitely don't argue. As she works through her anger, she'll be more open to hearing about your hurt.
It's taken almost a year of separation, but my W is only now expressing regret to me about her part in our marital problems. Previously it was all my fault.
