Saturday my MIL came over while I was out doing some shopping. DH was doing some yardwork with his dad so she decided to take a look around the house. When I got home she comment on our bedroom set and I figured DH had taken her around the house. When we got into bed that night, the sheets were tucked under the mattress (I don't make the bed that way). I asked DH if he remade the bed from when I did in the morning and he said no. I asked if MIL had when he took her on a tour and he said "She was in here?" I'm a little creeped out that she would remake our bed, and I'd really like to set up boundaries- like don't walk around our bedroom by yourself without us saying "hey, wanna check out the bedroom." It was one thing when we weren't living there, just remodelling before the move in, but now it's our home. I don't want to worry that MIL and whoever she's bringing on a tour will see my dirty underwear in a hamper or whatever. It's an uncomfortable feeling.
She's notorious for making herself comfortable at other people's houses. DH's aunt was horrified when she caught me being dragged on a tour of their bedrooms and basement storage room the first time I went to their house for a cookout.
How do I tell DH that that is not acceptable and that he needs to talk to his mom? I don't think he thinks a thing of it, and even supplied her with a garage door opener. I've come home to see that she's been there while we were at work, because stuff will be moved around. I see the benefit of someone else having access to our home, but I feel like our privacy has been invaded.
