My mom and wife are like this. I had to talk to them openly how I need my quiet time as I'm an introvert. I had to talk to them many times before they would remember this, you can expect to do the same. So why can't you go somewhere else in the house or yard to relax?
Women need to bond with people like friends or family and this often involves talking. Sometimes it's a steady garden hose of talk, but sometimes it's a giant fire hose of talk that just bombards you. You could be sensitive to this if you are an introvert. And if you don't talk to them enough, they think you don't love them and might actually leave you. This is superb ignorance on their part, but you don't really want to stay with a woman that ignorant do you?
Just make sure to talk to the mom about this very openly, but be polite. She might have really bad insecurities and that's how some women try to cover that up. And some just like to talk because they are more social, especially with people they like. So, it sounds like she likes you! That's not all bad.
As far as her sense of humor goes, you have to learn to live with people who are different from you. If you don't want to hear the jokes, go to another room for a while.
