OP errr I don't think I understand but WTF has wahtever she does with her dress got to do with you? First you said you were worried for her, now it appears you are miffed because she is selling a dress that you had to hold the train of.
So what?
If her marriage is in dire straits why is it your business
If she is just an unsentimental money grabbing cow , why is this your business
definitely not worth you losing the plot over.
My dd bought a hollywood dreams dress worth 1800 pound , In a sale she paid 360 pound for it and sells it for 1000 pound , well over 600 pound profit .
So shoot her.
yes she thought the dress was the most beautiful thing and she loved loved loved it and she had me traipsing round with her for much more than three weeks, bloody hell , it was more like 9 months, me and her poor patient bridesmaids dealt with every emotion going from her.
Did we get upset cos she sold the dress after all our hard work . Did we buggery..her dress, her choice, and she would have been stupid not to. She had the dress of her dreams and made a profit.
her marriage is just fine ,
her bank balance is fine
her mind is just fine
Yours however seems to be a little bit "driven"
Not sure what with though ...
but add another
to your basketcase
