Hey L2, Your sitch sounds oh so familiar. Except for the gender reversal.
Anyway, I just want to say that I completely understand not wanting to confront your H. I also have decided just to let sleeping dogs lie. Even though I am completely unhappy with the fact that my W is still here, I also am exstatic that I get to see my 2 Ss every morning and every night, no "visitation", etc. Mine are younger than yours, but still it is a great gift to give them two parents there for them every day.
It sounds like you and your H are cordial to each other at home, so I don't see why this is crazy. If anything, it is the opposite...a conscious choice to put the welfare of your S above your own desires.
Take care, SD
