You seem like you are in such a strong place, and still detached enough that you can look at your options and not worry/panic about the outcome.
I was encouraged by your IC saying infidelity takes a long time to heal from and you haven't had enough time. I'm much newer to this than you, so of course I am struggling as much as I am! That made me feel better.
It sounds like the approach you are taking makes sense. There is no rush. You working on YOU... that part of DBing needs to continue on into piecing.
