Mil drama!?

So I made plans with my mom about a week and a half ago for her to come stay at my husbands house the night before Thanksgiving so me and my mom could make thanksgiving dinner during the day. She's coming with my two younger siblings ( big age gaps). My in-laws were having issues with their truck and told us weeks ago they couldn't come up. Well about a week ago my mil called and told me they might be able to come for a late thanksgiving ( a couple days after thanksgiving). I said that was fine just let me know. So she called me today and told me they were coming up for thanksgiving with their dog and they're going to stay the night. I was taken aback a little and told Oh well my mom and siblings are staying at our house but you guys are still welcome to come for thanksgiving dinner.( our house is way too small for everyone to stay the night) anyway she got mad at me and said they couldn't come for Christmas and they couldn't come a day later or work around it and she refused to get a hotel room even after I offered for my husband and I would pay for it. She then started crying and was all upset and said "don't worry about it". So we got off the phone and she sent me a text saying they wanted to come still but they wanted to stay the night at our house. Right after I already had the same conversation about this on the phone with her? I said the same thing I did before, that we already made plans for my mom to stay with us. She then got mad and said we will see you after the year. ( keep in mind our house is tiny, 2 bedroom and one is our babies room so we have to set up an air mattress in our living room when someone stays) im very frustrated because I'm the bad guy even though she was very last minute and told us several times they wouldn't be here and now being angry at me because we made plans with my mom and I told her she was still more than welcome to come. Anyone experience this crazy behavior from their mils?

Update: she just called me again and was yelling at me basically about me making plans already and how much she does for us and not being able to stay at our house. But she made sure before she started to ask if my husband was home with me...
