can't say what stage you are in, but you sound a lot calmer and more centered.
A part of you is realizing that your life will not end, no matter what happens.
At first that can alarm you, b/c you fear you may think you no longer care.
But my bet is, it's a healthy detachment and doesn't have to be confused with apathy.
We know you care. And you are putting the right focus on your son.
I think the more you build on these momentary bonding experiences, like interacting with the friends or uniting to support son (flu's can be very dangerous for little ones), the better. So carry on and see what happens.
You are building a foundation for your future r,
no matter what that means, you will have to communicate for life.
Most of your post is positive progress, imo.
