Maybe, but I'm pretty sure he will at some stage. Then he can do the whole 'I tried to find you' spiel again, trying to convice us that its all MIL's fault. (Who lived in the same house for 10 years & he actually visited her in that house - once, so he knew where they were she's only moved once since!)

DH's sister knows that the kids don't know & understands. Maybe if she & the girlfriend come too I'll survive?
