“I’ll meet a new and improved version of you after I move!” Your friend waves to you as they pack their things in a moving truck.

You find yourself taken aback by their off putting words, but according to research, it seems friendships are becoming more disposable in mobile countries like the United States.

Dr. Omri Gillath, the author of the book Adult Attachment: A Concise Introduction to Theory and Research, comments on how our mobility changes how attached we are to certain objects, which eventually translates to relationships. Because moving in the modern age is linked to higher rates of success in life, individuals are more likely to have shallower attachments to objects and people.

“…If you know you’re moving and develop the idea that everything can be replaced, you won’t develop same strong and deep ties. We’re suggesting this is a broad phenomenon where all tend to look at relationships to co-workers, friends, and social network members as replaceable,” stated Gillath.

Viewing relationships as replaceable may seem like an easier way to cope with change, but in reality, “deeper, high-quality [relationships] provide us with the kind of support we need like love, understanding, and respect…[we] need these very close ties to feel safe and secure and to function properly.”
