"In a relationship"

Just cause you're "taken", it doesn't mean that every person in the world who isn't your significant other is trying to get at you. I don't see any harm in casual or deep conversation. If your significant other gets insecure about it, you're digging yourself a hole by being with someone who is limiting your capacity for living life. And if you think you don't have the right to speak to others because of that reason, you need to reevaluate your life. Being stripped of freedom for the sake of this thing we call love is silly & something YOU WILL regret. Human connection is important emotionally, mentally & spiritually. And the more people you are able to connect with, the better off you are in every aspect of your life. You're full of yourself if you think everyone wants to get with you.
