Have to travel 200 miles to visit in laws for xmas tomorrow. We are finally debt free and have a dog so can't stay in a hotel as we cant afford the expensive dog friendly one near her. MIL has a 3 bed house with two double beds, a single bed and a sofa. We asked if it was ok if we stay. The in laws and my teenage children can have the double beds, I sleep on the single bed, dp has sofa. She has point blank refused and said one of us needs to sleep on the floor as she needs the entire double bed to herself as her back hurts so my fil has to sleep on the sofa. Is she being difficult on purpose? I've always had a strained relationship with her and it seems like she's being deliberately awkward.
