Hi Lost - Yes, we talk about this - many times in fact. This was just one of those situations where he said something unkind and hurtful, without even thinking and I reacted immediately, even if I didn't over-react. If something like this happens again, (as mentioned by others in this thread), I am not going to give him the satisfaction of my reaction. As hard as that may be for me. Walking away is not one of my best attributes!
And the "love letters" - well, I have a box full of them. I often write to him when I feel I have no other alternative. I don't know if it has ever helped him, but writing about it has certainly helped me in some way.

Thanks for your kind response!
