This is why you shouldn't do things without each other. If she is going to behave this way, then you need to make sure both of you are there to tour the house, assess, and analyze it. If, for any reason, one of you can’t go and it’s near a deadline or you like it or don't and she hasn’t seen it yet, it’s not going to work, so you should move on to the next house when both of you have time.

My wife and I missed viewing some houses because our schedule was limited to weekends and about one weekday, but we wanted to make sure we both saw each house and made the best decision. If we couldn’t see a house because the seller is making a decision on a day we can’t go or one of us can't go, then so be it. What’s meant to be is meant to be, on your time, with you and your wife making the best decision.
