Disrespectful??

Hey, so my boyfriend and I have been dating for what gonna be 1 year on the 11 of July. And he had just told me that his mom complained that its disrespectful when we lay on the couch to watch TV. Granted we for the most part do it when they're going to bed, nobody else is there, and it's extremely innocent, I usually go to sleep. We've been doing this for quite a while since around the beginning of our relationship, she could have said something then but it's now. Now I respect her wishes of us not laying on the couch but is it really disrespectful? I would get it if we were making out or something but it's just to get comfortable to watch TV. Let me know what you girls think. Oh! I also believe it's cause she told someone and they said that its disrespectful. But yeah let me know what ya'll think ❤️😘
