Hurt... it is your life...your MR. I know how you feel, about wanting to say your piece. I think of things I would like to say to my H all the time. The thing is, it won't make a difference. He is fully immersed into this new life of his and me having my say will only push him further into it. Despite me knowing this, I have still found myself saying things to him that I later regret. Thankfully it hasn't happened for a couple of weeks now which means I am definitely making some positive steps.
If writing that text has helped you to move forward, then I can't fault you for it. As long as you sent it with zero expectations, then it doesn't really matter. Again... the DBing is for you... not to bring her back but to make you more immune to the crazy ups and downs of this forced journey you are on. I feel like I have made some really good gains in the regard lately but I know that there are going to be more challenges to come and more opportunities for me to say things I probably shouldn't say. I am hoping when those times arrive, however, I will be way less likely to say them. I like you last paragraph. It is a good plan. (((HURT)))
