I recently sold my beloved home of 28 years and moved to a different state. I felt terribly bereaved for the first few months, but gradually began to feel better. Then just yesterday I heard from a former neighbor about how much the new owners were loving the place. My reaction surprised me -- it was exactly like hearing about an ex-lover and her new beau, and how in love they were.
Attachment is attachment, whether it's to a dwelling, another human, or a bottle. To me, telling someone to "just get over" feeling an attachment to a place is like telling an alcoholic to "just get over" the compulsion to drink. Your brain doesn't know the difference. In either case, the solution is the same -- time, effort, and the development of new, healthier attachments to replace the old ones.
