Honestly, a verbal apology would be irrelevant to me. I don't know whether that's because I'm used to being told 'YOU want ME to apologise?! Who do you think you are? Get over it'.. But actions speak much louder than words. Is he in 12 step? I assume when he reaches step nine he will make amends in whichever way he decides is appropriate. But expecting an apology won't achieve anything and will just make you feel resentful.
