How would you take it? Sorry not "glow" related

So we are on our Road trip to drop off my husbands son in AZ to be with his mother and while we're driving my husband tells me that he got a phone call from his ex-sister Inlaw and she had said we could stay there overnight. He decided to tell me as we're driving to AZ, I had bad encounters with his Ex wife and don't feel like staying there. What would you do? How would you feel? I know this is not "glow" related but I needed to get this off my chest...
