Is this the end of my marriage?

[P17]

Draft 2:

"
I will no longer accept your A and continue to keep the truth quiet about the damage it has done to our marriage and our family.

Having a constant reminder of the life we once had and the future that is now gone does not allow me to move on with my life. I cannot forget the last 7 years of my life with you and need time and space to heal. I am concerned that D is expressing anger and resentment that you left and she too needs time and space to understand her feelings.

I have made many changes over the past few months and I'm determined to continue my growth into the best Father and man that I can be.

I have been thinking about all of this and I have decided that there should only be contact between us for two reasons. To either discuss the reconcilliation of our marriage or the potential end of our marriage. The first one I can't discuss while you have invited a third person into our marriage and the second one is best left to solicitors I think. In the meantime, I must move on with my life without you.

Would this be best put into a letter and sent to her rather than said?

I have been looking at the Marriage Builders forums and they have a Plan B letter. While I don't feel it's loving theme is appropriate for my sitch (as I've already done the huge love letter thing) I do like the idea of sending it to her instead. Not completely convinced though.
