Pay attention to whom your friend is spending time with. If you realize that she has acquired a whole new set of friends and rarely includes you in their activities, be proactive in attempting to integrate yourself into this new social circle. Recognize awkwardness for what it is if you are not readily welcomed with open arms.

Make attempts at communication. Call and email your friend in an effort to engage in the conversations you two previously would have enjoyed. Avoid becoming accusatory if he does not immediately respond, but be aware if it seems as though communication has been cut off completely.

Extend invitations to your friend that might be hard for her to pass up. Suggest dinner at her favorite location or a hike in an area of town you know she loves. Give her several chances to spend time with you, but if her answer is that she is just too busy, understand that this may be a sign of the low priority she is placing on your friendship.

Continue to live your life as you did before. Remain friendly when you see him in public and don’t avoid favorite spots or gym classes you two used to frequent together. Pay attention to how often you ran into him previously as compared to now. If you get the sense that he is avoiding you, trust that instinct.

Ask sincere questions about her life when you do get the chance to catch up with her. Strive to remain engaged, even as your fears of a faulty friendship are seeping through. After devoting some time to what she has going on, begin to drop hints about what is new in your life as well. Gauge her interest based on how she responds to your revelations and whether she seems to be paying attention at all.

Watch his activity on social networks. If he is remaining active and engaging with others while seeming to freeze you out, it is a pretty clear sign the friendship may be over. Prepare yourself for the day when he may just delete you as a friend completely.
