Hi @Colleen_Mc and welcome!
There is a way to integrate Facebook and your Fitbit account. You can find more information about how link your Fitbit and Facebook accounts by clicking here.
To be honest, I've never heard about somebody linking their Facebook account to somebody else's Fitbit account; but if you think that this is the case, you can log into Fitbit.com and revoke Facebook access to your Fitbit account here.
Hope this gets you back on track and let me know if you need any additional help!
