My mom does this with my step father. They have a really solid marriage and even though me and my siblings r all grown and moved out the house, they still sleep in separate rooms. They will do everything else together even watch tv in each other’s rooms. But they don’t sleep together. Apparently other older couples do the same as well. I thought it was weird but I found out even some older Hollywood couples have separate rooms from their significant other that they sleep in. Do u do this? Why or why not?
