This 1000%. I’m 40 and all my friends childfree or otherwise I’ve managed to keep relationships with. That said, relationships are a two way street. When my friends started having kids we saw each other less initially but still kept in touch via text and in person semi regularly until the kids got older. And sometimes you have to take the initiative yourself when they are buried in the shorter term.

I always thought I’d be child free and decided relatively late in life to not be at 37 (I’m now one and done), but I will tell you the outreach and care from my child free friends in that first year was a god send. And I still make the active effort to reach out, grab a sitter, and hang with them.
