We not shared a bed for over 4 years. We are still very much in love and close. He sleeps deeply, snores, snuffles and keeps me awake. I have baby dd in our room and nurse her in night. I get up in night with dc so dh sleeps and refreshed for work. I sleep well although lightly. So we are all happy, all getting sleep. So AIBU in not wanting to change it to "fit" what is perceived as better by my mother. She actually thinks that it's wrong for a couple to sleep seperately.
