Wellwobbly - great links! My favourite quote (from david clark) 'Did Nathan say David's wives and concubines hadn't met his needs?'
I think Chump Lady has it nailed.
And I agree with FrancescaBell - about several things - but especially about boundaries. We were not good at boundaries and I was far too generous about the behaviour of female friends. The only person who in any way attributed my dh's affair to me was a friend of long-standing who herself had an affair (it ended her marriage). She managed to avoid learning anything at all from the experience except that she was entitled to everything she did and that none of the theories about affairs apply to her at all in any way, even the statistics - she's unique. It's a miracle.
Most of her friends deserted her - not me - I am prime Chump material. I mean - WAS.
Other friend (of many years) was my dh's confidante - he didn't want to face a male friend who might not soothe his ego to the same extent. 'We must think of his needs,' she told me, at the point where the dcs and I were facing the possible loss of their father, home and way of life over a bunk up at a convention with an ow my dh didn't even care about. And later, disappointed possibly by dh's evident remorse: 'He shouldn't be sorry about the affair and I don't share your boundaries.' Out she goes.
This shit brings out the worst in people, like house buying or the disposal of a body.
On the other hand we have a great couple therapist who doesn't blame me and sees the affair as a distinct event, whatever else may have been happening (and I don't mind admitting to my faults). He is nothing to do with Relate.
