In order that the kids did not need to choose between being in their own home and seeing their parents. Kids stay in the house, parents shuttle. Not my choice, although I went along in my pre DB ing days when I thought appeasement would increase the chances of reconciliation. We were also in MC then too, although my WAW really never made the marriage the client.
The only way for this to not reset the clock (her clock) would be if she left the house if I moved back full time. as I said, she is adamantly opposed to that, & threatened family court if I did not compromise.
I think she did not want to move to apt is so the kids could still see her without having to choose between home and mom. But she has never really had to face the consequences of her decisions.
