FG, as you know I'm in a similar sort of odd calm as well. It's almost like W and I have accepted the inevitable and we're just going through the motions now. My brain tells me I should be sad about that, but inside I just kind of feel empty right now.
I find myself wondering if we're just going through exhaustion at this point. Wondering if, bc of the months of stress, this has just become our norm and our body and minds have completely adjusted to it. Not to dissimilar to how I'd envision a prisoner gets used to the routine of being in jail (aka in house separation).
End of the day though, it's about consistency. Do what you know to be the right thing to do, regardless of how it affects the W. Part of getting ourselves back.
Keep spending that time w/ the kids and keep strong for their sake brother. You're doing a great job of that!
