I deal with it by making providing a tiny part of my life. If I'm only seeing 2-3 people each week it's not hard to talk about the other 90% of my week with people. ("What did you do today?" If I didn't see a client today, I tell the truth about what I did today

Others have given relationship advice. I'll give friendship advice.
For close friends, I suggest you start meeting other providers and then find ones you click with and have COMMON INTERESTS with, other than just being providers.
You and I have gone to lunch a couple of times and I absolutely love you! You're beautiful, fun, intelligent, educated. And I really do appreciate you reaching out to me...but we don't have enough in common to build on.
I couldn't find any activity we could do together other than going out to lunch and that's not enough to strengthen a relationship because it just becomes an extra thing to schedule (especially for you as I know you juggle a regular day job). And we live an hour apart so even meeting halfway for lunch involves a 30 minute drive each way for both of us.
You like to go out to nightclubs at night. I like to stay in at night. You play tennis. I go to the dance classes at my gym. We go to nail salons in our own, different, neighborhoods.
We live quite a ways apart. ..especially as we live so far apart we can't do a spontaneous "Hey, I just brewed a pot of coffee and pulled a carrot cake out of the oven. Come on over."
The truth is that good girlfriends emerge from regular multiple contacts. In some ways it's easier to have girlfriends than a love-match, but in others it's harder (e.g. when there's sexual chemistry with a guy you're both willing to drive long distances and participate in activities you don't normally enjoy.)
Maybe post in the powder room with your location and a couple of activities you like and see if another provider who lives near you would enjoy those activities too?
Or, reach out to civilian ladies whom you're already in regular contact with and just don't tell them about providing.~~~ women in your tennis leagues~~ mothers whose kids participate in your son's activites~~~ neighborhood book clubs, etc.
