This has played out for me. A couple of friends moved away. We had kids and the ones that stayed didn't. I talk to one out of my four "close" friends on anything resembling a regular basis. I realized I hadn't spoke to one in 8 months. If you have kids and your friends don't, expect that to put a strain on your friendship because you won't have time to spend the way you did once upon a time. You will plan more because your time is no longer free, just borrowed from your spouse or whoever else is watching your children. You will lose those serendipitous moments that form the contours of your relationship. As an entrepreneur, I have found it really difficult to make friends. I have a business partner and a distributed team, it is extra hard to make new friends. If you work in an office, you come across people. I always found it easy to make friends at work and took it for granted. Now, it's nearly impossible to do. Then again, my mom has exactly zero friends and gets by so I have to imagine friendship is not a necessity.
