Goals #2 through #6 are fantastic. However, Goal #1 will make those goals, and any other goals, impossible to achieve (in my opinion).
#1) We have full forgiveness for everything. We both do what we need to do to be able to have a clean slate.
The thing is, all of your other goals, are ones based on connection, communication, honesty, integrity, vulnerability, authenticity, and so on. We simply cannot have those things without taking ownership and accountability for who we are and what we've done. Otherwise, we are simply rug-sweeping.
Please don't misunderstand me. I think what you are saying here is that you don't want this to be something you can't "move forward" from by getting stuck in it. You can move forward, and even build something much better and much stronger together, but that new relationship needs to be built on a frame of accountability, honesty, a willingness to own and grow from our mistakes, and a determination to be people of integrity. Forgiving each other, and ourselves, is a great step. Just understand that forgiveness, and a clean slate, are two entirely different things. Forgiving doesn't mean forgetting, nor does it mean that what happened was okay. Forgiveness is a decision we make in order to respect and unburden ourselves. It is never absolution. Either we learn and grow from the past, or we repeat it.
To be honest with you, speaking as someone who is 5 years into R, one of the most helpful things we've done is to see the infidelity as a "shared story". It is something that happened to both of us, a history we share, and while it is a painful and horrible history that we never want to repeat, it is also something we survived, together, and if nothing else, it is simply what happened, and that cannot be denied.
One of the very best approaches to building a new relationship together (and re-building our new individual selves as well) is to look back at what doesn't work, what failed, and what we regret most, as our guide. Lying didn't work out well, so we move forward as honestly as we can. Not taking ownership when we did wrong failed, so moving forward, we become authentic. Avoiding conflict only caused things to get worse, so moving foward, we talk about the hard things before they fester. So on and so on.
I know it might sound sad on its surface, and it is of course, but there is also something incredibly beautiful about two people, leaning into each other, surviving the unsurvivable together, and fighting like hell to make it work moving forward. That is a foundation that is rock solid. It provides for imperfection. It provides for failure. It provides for when things get tough again, and they will. It also provides for joy, and growth, and honesty, and shared emotions, and friendship, and love, and all the good things in life.
That's my two cents. Take what works for you and leave the rest.
