HappyChappy - thank you. I am smiling now

- you are absolutely right. It actually is a God send and we are at great peace because we are not subjected to her games any more (let's see how long it lasts - maybe a long time, yes). You are right in that this has been building up in her for a while. I think she has snapped. We have been very conscious in our interactions with her for a while, making sure that we did not react to her games and I think now she is resorting to the silent treatment as a result, in order to punish us. It's actually a good thing and also I totally agree with you in that she is using us as an example to the other siblings as a warning that they will also be punished if they do not supply her with her needs. The sad part is that we did try and make an effort with her in a loving, normal way but her games/ control/ manipulation just kept getting in the way so it is what it is. Moving on now, many thanks.
