I agree you should not involve family or friends in your quest to find out if there is OM or not. A P.I. is a good idea but she also could be having an emotional affair of some sort that is conducted online and that is why you see no evidence of a physical affair.
I also agree you should not talk to the real estate agent about your W at all. If the agent brings it up simply tell her you want to stick to the business of the house only.
Yes, it is time to do something MUCH different. I think you will feel much happier once you do!
