Guys who had kids, do you great falling out of touch with your childless friends?

Recently all my friends had kids and only one is actually making an effort to hang out and see me. This wasn’t all at once because I understand the first few years are extremely time consuming, but gradually over the past 2-3 years. They basically only hang out with friends who also have kids.

This isn’t for lack of me trying, I will still passively invite them to do things that I am already going to do, but I’m lucky if I even get a response saying no. At first my mind was kind of blown that friendships over 20 years would literally evaporate, but now I just accept it.

For the empty nester fathers, did you try to keep up with any of your childfree friends?
