Why it upsets you to see X in 'the brooms' car, I can't fully answer yet. I can sit here til the cows come home and say that the only thing about OM that upsets me is the unknowing interaction he has daily with my sons.
But writing this now, maybe I just found my answer.
Not only does OM interact with my children on a daily basis instead of me, but he interacts with XW as it should have been with me in front of them?
I think that's it. Epiphany, first thing in the morning.
