Is it normal to not want to cuddle while sleeping?
Yep.Totally normal
Yes, it’s completely normal not to want to cuddle while you sleep. Plenty of people love affection but sleep better with their own space, and it doesn’t mean you care about your partner any less.
Some people find cuddling cozy; others get too warm, feel restricted, or simply sleep better without another person pressed against them. Your preferred sleep setup is just a preference, not a measure of how affectionate you are.
