Wise words Jomarie I agree with you. He does tend to play up when I am feeling more incapable of doing things than when I am able. Which is a bit annoying because that is when I need the help more. But you are probably right. I do think he gets worried but won't say and deals with it by hiding away and trying to put some distance between us until I am better again. Trouble is, with my conditions, it is like a rollercoaster and I'm up and down all the time. Never mind, it will pass, I'm just very hard to deal with health wise, I know that.
I am glad that your son has seen the light and worships you now, you deserve it. His wife is just jealous, take no notice. 
Jing Thank you for your constant support and understanding. You have been a great help to me through all the problems I have had with him and tend to get me with what I am saying, thank you.
