Don't let them to get into your life.....I'm a terrible sleeper, but I really want to sleep with my partner in the same bed, it feels more intimate....
my ex husband used to snore like crazy, I couldn't sleep and we were sleeping apart....but that caused us to get really seperated....we barely had sex and then we start fighting....well...it ended up getting divorced....
I think that's why your family is concern....because they don't know about your intimacy part....since yours is fine, then sleeping in seperate room is good for you.....what makes you and your partner happy is count, not what makes others happy!!!!
and why did you tell them that you are sleeping in seperate rooms in first place?
