Clingy Mother-in-law

My brother-in-law is going on vacation for two weeks. During a few days of those two weeks my father-in-law will be working the night shift. My mother-in-law claims that she can’t spend the nights alone at home. That she would instead like my husband and I to come sleepover at her house, or for her to sleep at our place for three or four nights. Seems sort of normal right? There is a little bit more...

My husband and I both have a busy schedule with late work hours. My mother-in-law has never spent the night at our home. In fact we only have one bed. My mother-in-law also has a history of clinging to my husband and holding a grudge against us choosing to live separate from her. My husband and I have had multiple arguments over boundaries and expectations of our time when it comes to his mother. So there is a little bit of a history there.

In my gut, I know for a fact that she is just being overly dramatic and can truly handle being home alone. But my husband doesn’t see that nor would it be wise for me to say that to him.

They all just left my house and we’re making plans of her bringing over extra thick blankets to sleep on in my home. I value my time to myself and my private space at home. I need to stop this before it progresses. How do I get out of this? Help!
