So my mum told my sister that when we were younger she had an affair. She and my dad are still married and seem happy, though in the last few years she is much more dominant and he passive.
So I am not sure what to do or say now, I feel awkward that she has told my sister but not me - she will expect my sister to have told me but that's not the same as being told myself. I feel awkward that I don't know how much my dad knows or if he knows that she is speaking about it now. I feel upset as I hope I would never have an affair and can't respect people that do but realistically know things can't always be that clear cut.
Does anyone have any advice on how to handle this?
