Is this not possible or is it just that people change? Am asking as there have been several times in my own life that I've been shocked to discover things about people that I thought I knew well. On Mumsnet I see lots of threads about people having affairs or acting in some other way which their DP or others could never have imagined. In some cases it seems there have been doubts or red flags but in others it seems a bolt out of the blue. If you can live with someone, share their bed and their lives (for up to 30 years in some of these threads) and they can then seem to be someone you don't recognise at all..is that because they've changed or you never really knew them at all? Can I ask does anyone REALLY know you? Sorry for lack of paragraphs..on phone.
