Overview
One of your friends has suddenly gone missing, socially speaking. Your calls aren't getting answered, and your texts aren't getting replies. What gives? They might have some new things going on in their life. Maybe they are simply too busy to get back to you. Don't take it personally. And if they're hanging out with a new friend, don't feel threatened by it. You've got to curb any possessive impulses and know that there is plenty of room in their life for the both of you.
