Mil (long)

How do you guys deal with being in your home when your mil comes to visit and your husband is a complete mamas boy and is blinded by her. Theres been several stories about us. But one time she raised her voice at me with additude and I didn't even say anything wrong. All I said was he is with our son calming him down and he will be right down. And she said that he has to be down here because the family is going to make an announcement. I said that he will be right down and his dad (her ex husband) wasn't going to make it without him. And she kept arguing with me. I told her I'd go get him in a little while. She just kept repeating the same thing. I tried not to explode. I let him know month after because he gets sensitive about his mom. He said I should feel honored because she's comfortable enough to talk to me normally and thats how she is. Nope. I told him that if that's the way you guys allow her to talk to you guys fine, but not me. He got mad at that. He gets mad when I say something normal like, your mom listens to this guy right ? He said I should never speak of his mom and keep her name out of my mouth. I honestly told him that if it has to do with the conversation and I'm not even saying anything negative. I don't see anything wrong with it. I'm ranting on but she's a pain and has done little sneaky things and I feel like she just can't let go of her son who is almost 40. I understand thats her baby but its to where his sister even says their relationship has always been strange. Anyways, how do you guys deal with a mil when they come and visit or you visit ?
