gustheguidedog I think you have misinterpreted what I originally said. Harsh comments if you meant it.
Everyone, thank you so muchfor all your support. I've got no idea what happened in October but she stopped phoning (usually we would speak every day) and she went out when we visited which I thought was very strange. When I queried her behaviour with my son he said that it was because I was still seeing ex DIL and had invited her out to lunch (with my GC's as well). Not sure why she took offence at this as she knew that I still had a relationship with ex DIL and knew of previous get togethers. I was often staying overnight with the GC's if ex DIL working away and son's partner said to me that I was being taken advantage of which I disagreed with as I loved looking after GC's.
Son and partner have no children by the way and son doesn't want any more children he says. Maybe it is this, I really don't know and like I said before, as long as we continue to have relationship with son I am happy!
