No. I don't suspect an affair. What about the 'space' idea? No apartment ... weekends at my Dad's or every other weekend ... if I'm home when she doesn't want me around, I feel likely to fall into an old habit or slip and give her justification for not wanting the marriage to work. Last night, for example, I gave in this thread the example of the house not being 'show ready' when people were coming to look at it.
