Married couples having separate bedrooms - Ideal or not?

Source

Hello fam, So there are issues with people liking different room temperatures, some like soft mattress and others hard ones. Lights off vs light on, snoring, sleeping with music on or sleeping with no noise. Watch Tv in bed, etc.

My mum's friend is always complaining about her husband snoring loudly every night and how he prefers the light on but she likes it off. She also says she keeps suggesting they stay in different rooms since he's not in for some sort of compromise(turning the light off sometimes) but he doesn't budge, saying he's the man of the house and as the woman, she has to give in to his. I was thinking of what to post on steemit and i thought of my mum's friend then i decided to throw a question instead and know what you guys think; is married couples having separate bedrooms ideal? or is it best to giveup what you want for your partner

Please your comments would be really appreciated, Thanks
