My kids came home from a week at their father's house today. My 7yo seems out of sorts and gets teary, saying 'I want dad to live with us. Why can't he live with us anymore?' And I explained that dad and I fought too much when we lived in the same house and that we had stopped being friends but now that we don't live together we don't fight anymore.
My son then says to me 'well dad says he doesn't live with us any more because YOU stopped loving him.'
While this is true, our 7yo doesn't need to be told this sort of stuff. It's playing games with his head and isn't fair on him. My XH is a total douche who has made my life hell but I don't tell my son that, regardless of the fact that its the truth.
