Mostly what they do to Henry is undermine Helen - yes Henwee come hunting with me, yes Henwee mummy is a liar, yes Henwee you can have chocolate. So he probably won't runaway unless he is left with horrible mummy
DDD you asked what Kirsty could say to make Helen see. I'd say play it the other way.
K : Helen I am really sorry for getting it totally wrong. I thought you seemed really unhappy and jumped to the wrong conclusion. I see now Rob is really good to you isn't he?
H well...yes
K: the way he looks after you it must be great not working. Feet up.all day...
H well...I'd quite like to work.
K you know we should do something.
H that would be nice
K wouldn't it be great if Rob came too. It's time we buried that hatchet.
H ...oh Rob's far too busy maybe just the two of us...this time.
Etc. Just let it all tumble out.
If people push her about her eating or his behaviour she will go on defensive and stuck up for him/ go into denial. But she now finds it hard to agree with people who are praising him.
Minimising is second nature if you are confronted. Personally I felt I had to defend my choice to get into the rs in the first place. If he was an irrideemable shit then I must be a fool.
But if I was left to moan I could bitch about things he'd done all day
and always expected friends to say oh yes mine does that too...only they never did...they just looked shocked. Except on the EA thread where pretty much everyone said oh yes they all do that as if (boaky tongue for starters) as if they all went to the same course in fuckwittery. (Not a course I'd recoomend for Ed)
Kirsty needs Helen time to tell herself he's a shithead.
