My experience with friends who moved away really resulted in us attempting to communicate a lot online. For friends that I had very strong bonds with, we would try to stay in touch any way we could and attempt to visit each other. Friends who were just ok, eventually, we just slowly stopped talking as often. You just have to accept it and move on.

Yes, most of my friends are in my area. I communicate with them online/text and we try to set up things to do (even if it's just grabbing some lunch).
