Thanks @BenHarper I did not see your response til now.
When I said your lady was lucky I did not mean to minimise her pain, but that she has someone to care.
Oh yes it is a very legitmate interest, but it was something about the way he engaged with me on it that worried me. We are now in a full blown episode 3 weeks later. It is his 2nd episode, his first was 3 years ago. It is serious enough, that it is now out of my hands and I have to pray that the justice system can help bring about some justice.
I am a greenie who did Geology 30 years ago but refused to work in mining. My son was engaging with it on a very current and well documented level, but it was the level of fear he aroused in me that aroused my concern re his MH, just a sign of how close we are, I guess. So that week I went to a lecture at my old lecture theatre and took the temperature of the best academics in our country, did a lot of research and pulled back my fear level regarding selling my house and moving to the mountains. I had an agent value our house so all was transparent for my son, so he could see what our various options are. I guess I am now trained in reality testing as his dad had schizophrenia.
But for now I have to get a team on my son's side and will be tied up with his GENUINE needs for a while.
