Would've left it at acknowledging the hurt. The stab about 'I'm sure we can learn' etc could sound sarcastic and from her warped perception she's thinking you're accusing her of not wanting to be agreeable or work together. Which she then feels she needs to reiterate to you, by saying she wants peace & to move on. Just reaffirm and show appreciation for her willing to meet you. 'Thanks so much for your reply. I know you're working hard and I appreciate you helping me get through this difficult situation. I want you to feel peace and happiness too.' Something like that...
