"H, the texting last Sunday isn't going to make me never trust you again. But you are right that building and keeping trust will take time, honesty, and transparency. Thanks so much for sharing the texts with your friend, it did make me feel better and I hope you got some sort of closure there. Even more important was the direct reassurance and comfort that you gave me — that is probably the best way to respond if I have that kind of reaction to something like that because of the last couple of years. I believe it will get better and your reassurance and honesty is the best way for me to heal. So, you did great and I feel really good about how that all went.
In my own effort to be direct and honest, I really just need to share very clearly that I really meant what I said — I feel violated when you introduce that friend into aspects of our lives beyond business in any way. It really doesn't work for me and it damages our relationship."
