And she lost all priviledges to take relationship readings when she started cheating on you.
No one having an affair should be permitted to ask "Are you OK".. its just a desperate attempt to soften THEIR GUILT.
The probelm is as you pointed out, its a trap. if you say NO, they feel GOOD that they are missed, but they will keep cheating.. if you say YES, you just validate what they are doing and they again feel GOOD that they aren't hurting you.
It's a VERY difficult rope to walk..
My advice is to change the subject
WIFE : Are you OK? MAYNARD : I have a busy day planned, can you hurry these people up and get these things moved? I don't have all day.
Don't say it with anger or with you looking away from her. Just look right at her calmly and tell her to get her crap out of your house.
