MIL made strange comment

I love my mother in law but today I was upset over a comment she made. I told her that my husband wakes me up lately because I've been snoring (I'm 35 weeks pregnant).he wakes me up because he thinks I'm uncomfortable and he says he's scared I can't breath when I snore. I don't mind him waking me up. My mother in law said I should sleep in the living room so I could let him sleep. We both have full time jobs and we've never slept separately. Even when we are mad at each other we sleep together. When she said that I laughed so hard and she said she wasn't joking. I told her if her son was really bothered by it he could sleep in the living room. Β She gave me a weird look and then suggested I sleep in my sons room if the living room wasn't comfy! I gave up arguing so I stayed quiet. I feel like telling my husband when he gets home but I rather keep my mouth shut. πŸ˜‚πŸ˜‚πŸ˜‚
