Is this the end of my marriage?

[P17]

I have come up with a 'speech' to say to my W about ending contact. I have to say I have my doubts it will attract her back to me, but I also understand that it's not actually about her.

At least here I agree as during the period where there has been little contact I start to feel better about myself. I miss my wife and still love her deeply but I do have a better attitude about life. I therefore know that NC is really the only way to go for me at this stage. However, as I have also said in the past posts, I feel that this is the last I will ever hear from my W. That is sad but that is also her choice. She knows where I am and can. at any time, decide that her M is worth saving. She always feared being a divorce statistic (something I only found out about recently) and she has this power in her hands.

Anyway, here is my speech:

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

It is unfair to continue to give D false hope of us being a loving family again and she has recently expressed anger and resentment to me about you and OM breaking apart our family. D has been greatly affected by this and she hasn't begun yet to talk about how she really feels. However I am worried that while you have contact with her and the A continues she will continue to feel further confused and angry about you and OM. D does love you, that is clear, but she is only 8 and I don't believe she can easily express or understand her feelings of love on one hand and anger and resentment on the other. To allow her to continue to feel like this will be to her detriment. You chose to give up the responsibility to be D's step-mum and I now realise how unfair it is on D for you to continue in that role.

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 will move on with my life without you.
"

I used part of what PDT said to me previously.

I feel it is a bit too long in the middle. I want it to be as concise as possible as I, as people who have read any of this thread will know, have a habit of rambling on. Short and to the point.

My D wrote a letter to my W tonight that I have sitting ion front of me which is basically saying she is sad since she left and wants her to come back as she really really misses her. I was wanting to show my W this letter to expose what she has done to my D. I feel this will push her further away though than bring her closer however she MUST realise the consequences of her actions. For all intents and purposes her step-D has always been treated like her D.

Again, comments or suggestions really gratefully appreciated.
