Thanks for the reply. You indicated that your relationship is still young, 3 and half years.
I don’t know what the long therm psychological effect would be in average person.
It took 3 years for us to “slide” from love loss to separation and finally divorce.
Sleeping in the same bed keeps “togetherness” on track, I think!
Sometimes one partner is away from home and returns during the night. It is nice to find your loved one next to you in the morning. Needs no touching, nothing!
There are little things between couples. I would call them nonverbal communication.
How important they are is a mystery for me as we are all different and never know the total truth.
Just because we are different, some of us develop different habits!
Good that your mutual love remains there. Without love many other qualities become meaningless!
