Ok so I need some really good advice. I began dating the most incredible man two years ago. My dad has been sick, and recently within the last month past away. Anyway when I met his adult children, a woman and a young man,,they were amazing with me. I thought I WAS the luckiest woman alive. 3 children of my own still teenagers, loved them and they loved my kids. So my fiances daughter was great , saying we should marry , called me mommy,,,his son phoned me and said promise me you will look after my dad, to which I said of course. Then all hell broke loose.
