Please answer. am i socially retarded? i never rekindled friendships from college or since then except a couple on facebook.

You are not alone: Life gets busy and most of us have enough in the here and now to more than fill our plate. My hat is off to those who can maintain college friendships and high school and junior high friendships. I can't as I have a life in the here and now. Dont feel bad. Enjoy the relationships you have now and the ones that really count you will hold on to.

Not unusual: People change over time and what they desire/need in relationships can change as well. It is possible to grow out of relationships. On the other hand, connections are vital to well being, and the main concern would be if this applies to your current life as well and the extent to which you are isolated/lonely. The number of connections is of less importance than the quality of those connections
