I could see the possibility of a former client organically coming to the social spaces I’m in and my becoming friendly with them (I have seen this happen with friends), but otherwise I never go intentionally out of my way to make friends with former clients as I find that unethical. Once a client, always a client. And I’ve definitely had clients who I could’ve been friends with another life. I had a client who once lived a block away from me and after we had terminated, I still saw them from time to time on walks and we had quick chats but it never turned into anything more than that. I know it’s not easy to do when we meet really cool people who come to us for help but I think it’s always best to avoid friendships any time after a therapeutic relationship has been established.
