AITA for not letting my mom come over while my friend is staying with us after what she did at his wedding?

My friend, Chad, got married last year and my mom and I got an invite. I wasn't the closest with Chad, but he was in our wedding and one of my wife's best friends is his wife's best friend, so it made sense to go. <br><br>I asked my mom if she wanted to come with me and she was excited. The wedding was out of town so I told her that we'd stay in a hotel for a night and come back the following day. The morning before we were set to leave she asked if I had also gotten her a +1 and I said no. I told her that all the seats were already accounted for because of how many people were going and she got pissed. She started freaking out and yelling that she needed to bring her boyfriend (she's been dating him for almost 2 years and it's very serious) or she wasn't going. I said she could go with him but I wasn't going to get him a seat at the wedding. She thought that was ridiculous and asked if she was just gonna leave him in the hotel room the whole time. I told her that it wouldn't be a big deal since the ceremony and reception were only going to be for a few hours and she could hang out with him after. She said fine, I got him a seat, and the problem was solved.<br><br>I just forgot about the whole thing and moved on. This year my wife and I moved into a new house and our friend Chad and his wife asked if they could stay with us for a week or two. Their house is being renovated and they can't move in until it's done. My wife and I have a 3 bedroom house with an extra room that has its own bathroom so it was no problem. They could stay for however long they wanted.<br><br>My mom saw a picture of them in our house on my wife's Facebook wall and asked what was going on. I told her that Chad and his wife are staying with us for a bit until they can move in and she asked how long they were staying. I said they didn't really know but they were staying for a few more weeks for sure. She got really quiet and said, "oh, so they'll be there when I come over?" And I said that yeah, they will probably still be here. <br><br>She asked if that was okay and I told her it wasn't really up to her. She asked what I meant by that and I told her that she saw how big of a deal it was for her to come to his wedding and that she was pretty disrespectful when she came uninvited. I told her that I'm not gonna try and get her an invite into our house while he's staying here. She told me that she was my mom and that I couldn't keep her out of my house and I said she was right, but that my house wasn't the only thing I had control over, I also controlled who was invited into it.<br><br>We've been arguing a little about it ever since but I don't think I was in the wrong. AITA?
