An addiction implies you have no control over your actions. In this situation, however, you do. Yes, you may become easily attached to people, and yes, you may feel the urge to poke and prod when you want to know what they're thinking... but you CAN control your actions. When you catch yourself thinking about a person more than you believe is "normal" or "healthy", find another activity to take your mind off of that person. When you find yourself tempted to ask questions you shouldn't, stop and think about what you're about to do and how that could negatively affect your friendship/relationship with the other person. I know it's hard, but I believe you can control this. =)
