I know what I need to do--let go of the past and things I can't control and choices he made; get through the present one day at a time, and focus on the future.
I recommend reframing that a bit.
We live in the present, the 'here and now'; there's no way around that. At this point, your here and now is probably full of anger, grief, fear, shame, whatever. My reco is to embrace the pain - let it flow through and out of your body. The more you do that, the more you'll be able to make the decisions you have to make for your future. A good IC can help.
A good MC can help, too, but most MCs deal with systemic issues, not with issues each partner has that interfere with the M. If your MC wants to deal with 'communication' and not the A, they're probably not giving you the help you need the most.
Among other things, at 10 weeks out, you're probably still in shock. Human beings don't make the best decisions when in shock - the amygdala has too much control. So I recommend treating any decision you make now as tentative and subject to change without notice.
It's been 14 years, and I still remember the explosion of thoughts that ran through my head during the 1st 3-6 months after d-day. I made millions of decisions. The trouble was that I'd think of a million of them within seconds, and many of those would-be decisions contradicted each other.
Rest assured that your brain will calm down. The calming has probably started; it will proceed if you let it. It will take longer than you want it to take, but my reco is not to force yourself one way or another. Go with your flow. Have faith that your brain is just responding to a trauma - and remembering anything else in your life that was traumatic. I think the need to process the trauma out of your body is the reason others have recommended an IC for you. I do, too - a good IC can help you.
Now is a time to start thinking about spending the rest of your life with your WS. Maybe you want to; maybe you don't. If you don't, now may be a good time to call it quits. Your H says he wants to build a new M, but he may not be willing to do the necessary work. If that turns out to be the case, my reco is to choose D.
But if you're both willing to do the work, R is eminently possible, and IMO and IME, it's very rewarding.
Another reco: look deeply inside to find out what you want. Both D and R are difficult, but they're extra-difficult if if you choose an option that you don't want. (Even when the WS chooses D or refuses to do the work of R, the BS can fight the or embrace the outcome of the M - and fighting is harmful to the fighter.)
Shock usually seems to last 3-6 months. Don't push yourself. Again go with your flow.
