Hi peeps. I set boundaries and tasks when we're alone. If DW is present, it used to be the case that she would countermand them, do them herself or say I was being a bully. This could be something as minor as passing the salt or the peas at table; DD in the recent happy phase would actually have to wrestle the food off Mum. It has got better: DD has been brilliant recently and DW has taken a step back. I fact, DD suggested that we go on holiday as a couple this year and she'd stay at home because the arguments on holiday were so bad. DW agreed and we booked the holiday of lifetime for next month. Hmmm.
Last night I didn't interfere because if DW is actually showing backbone my appearance would make it disappear. I dried her tears, hugged her afterwards, we went to sleep.
Everything seemed fine this morning, but at some point DW must have gone into DD's room and been grunted at. I was shaving and there was a load of crashing downstairs, door slamming and the car being driven away at speed.
DW will not disengage. I don't think she can; we didn't go anywhere as a couple for about 9 years because she'd fret constantly. We tried early on with a babysitter and she just cried in the restaurant.
I do know she has real issues with attachment, as MIL used to let her cry for hours as a baby.
As for breaking the marriage rather than the family, the next bit might get me flamed.
I chose DW, and she chose me. DD was given to us. It is my joy and my duty to bring her up as a human being, but I've always known that one day she'll be gone. DW and I are together for life, or that was the idea.
Right now DD is cleaning downstairs, I've just finished the bathroom, we'll have lunch like civilised people.
