[. If he attempts contact or 'wants to talk' then maybe I will consider it then..
RW, that would be a terrible idea. Most waywards will "want to talk" when they see that you are serious about Plan B. It doesn't mean anything other than they don't like losing control of you. What Plan B specifies is sending a Plan B letter with your conditions. You shouldn't agree to even speak to him unless and until he meets all those conditions. Otherwise he is wasting your time and wrecking your emotions.
I will post a template you can use. In your case I would add the conditions Dr Harley told you to follow and that is a) anger management training, b) sobriety and c) eventually marriage in order to reconcile. If he won't meet those conditions you are better off without him. I would write your letter and post it here so we can give you feedback. Here is a template.
Sample Plan B letter, from SAA (revised edition) pages 77-78:
My Dearest __________,
I apologize to you for my part in creating an environment that helped make your affair possible. I foolishly pursued my goals without understanding my responsibility to meet your most important emotional needs. I was not there for you when you needed me the most and we are now both suffering for my mistake. [Add your willingness to address other complaints that the unfaithful spouse may have communicated prior to the affair.]
I am willing to avoid the mistakes I've made in the past and create a new life for both of us that will meet your needs. But I cannot do that until you end your relationship once and for all. Living with you under these conditions has been the most painful experience of my life, and I can no longer endure it.
Until your affair ends, and you are willing to follow a plan of reconciliation with me, I will avoid seeing you or talking to you. Our friends, ________, have agreed to help make arrangements for you to see our children on schedule that is mutually convenient. They will provide transportation. If you want to communicate about the children or any other matter, it will have to be through them.
I ask that you respect my decision to separate from you th is way. You must know about the suffering I have endured because of your relationship, and I simply cannot be with you any longer knowing that you are together. I still love you but I cannot see you under these conditions.
As soon as you are willing to permanently end your relationship, follow precautions to avoid absolutely any contact with the other person, and join me in a plan to restore our relationship, I will be wiling to discuss our future together with you.
I hope that we will be able to rebuild our marriage some day. I want us to be able to meet each other's emotional needs and to avoid doing anything to hurt each other. We can build a new lifestyle together in which everything we do makes us both happy. Then there will never be a reason for us to be separated. I want to be your best friend, someone who is always there for you when you need me. And I want you to be my best friend.
I cared for you when we married and I continue to care for you right up to this day. But I cannot be with you or help you as long as you are in this relationship.
With all my love,
This letter should be delivered by your friends to the unfaithful spouse, and a copy sent to the lover with a note at the bottom saying:
I love ______ with all my heart and am willing to do whatever it takes to make her happy. I will wait for that chance.
