I don't think your letter was harsh. I think it was direct, assertive, and respectful. She has a pattern of violating your boundaries and therefore it was important for you to be direct and specific. I think you did a good job of stating the pattern you see, giving specific examples, talking about your feelings, and restating your boundaries. You also talked about her strengths and what you value about her.
It drives me crazy that in our culture we have more tolerance for people violating boundaries than we do for people setting and defending boundaries. I am a therapist and I talk to my clients about this all the time. Here's the example I use with them- If I punch you in the face and you say "hey you punched me in the face and that hurt. Don't do it again" and then I feel bad. It's not your fault I feel bad, it's my fault for violating a boundary. When you don't set and maintain boundaries it enables other people's unhealthy behaviors and prioritizes their feelings over yours. But here's the catch, no one ever says "thanks for not letting me violate your boundaries anymore. I'm so glad I can't do what ever I want to you without consequences now." There's always a fallout, but hopefully she will come around. I'm a big believer in the idea that we teach others how they can treat us. I've played this role in my family a lot. Usually it's pretty unpleasant at first and then people start to interact with me in a better way. So hang in there. I think it ok to do what someone else said and acknowledge that it must have been hard to get that letter, but don't negate the boundary by apologizing.
