Thanks for your responses.
I'm feeling a bit better this morning.
"I think there must be much more going on here than just this"
There is. I'm clinically depressed at the moment from stress generated by dd's behaviour (she has been very difficult for about a year now) and by trying to get a diagnosis and some support for my younger child who I believe has autism. I know I am over reacting to this situation but it needled me in such a strange way.
" If he doesn't like something you've said or done, he should bring it up in private, and without being disrespectful. It should certainly never be done in front of children."
One of the things dd does when she's verbally attacking me (which she does often - every time I take her to task for something or tell her to do something she doesn't want to do, or stop her doing something she wants to do), is shout that nothing in the house is mine and I don't have authority because DH's salary pays for everything. I know I shouldn't let her stupid comments bother me but they do. I feel diminished by her repeating that I haven't achieved anything with my life. I know it isn't true - I have a great part-time job that I love and worked hard to qualify for, which pays well for the small number of hours I do, and that even if I didn't work that DH and I are financial equals in the marriage by virtue of the fact that we are partners. But I can't seem to shrug it off. Probably because I'm depressed and oversensitive.
DH does back me up with dd when he's here.
Personally I just don't 'get' the English secrecy over money (even though I am English). If I'd realised he felt strongly about it I would have kept my trap shut. But as it was just mentioned in passing in the context of a discussion about mortgage multiples - I mean, why the concern? He hasn't been able to explain his upset over it. Can anyone else here explain why you'd want to keep this information private even from close family members? Is it about shame? Not earning enough? Modesty? Not wanting to flaunt your earning power?
Particularly when most people I know have no problem with conspicuous consumption which is in its way just as revealing about your income, and even more revealing about your values when it comes to money and spending.
I do feel that being squeamish about these things is prissy and all about being 'naice'. And I'm not used to thinking of DH as being prissy and 'naice'. It shocked me to look at him that way.
"The best solution of all (don't laugh) is, send her to boarding school."
Myself and my two siblings were sent to boarding school at 11 and it was an disaster for all of us. I personally think my sister's alcoholism has its roots in the emotional neglect she experienced at school at this very sensitive point in her development. I would no more put my children in boarding school than I'd put them in care. I think teenagers need to be parented, and they don't get parenting while in institutional care.
