Like even if you're dating/attached w someone you shouldn't stick with them every single minute, and just treat them like your good/best friend and give herself/himself some alone time sometimes. You give him/her "me" space by understanding that its absolutely ok if she/he doesn't reply you at times, by letting her/him go out with whoever she/he wants, and basically not ask them to be with you 24/7. "Me time" is so important.
