How to deactivate a google account without deleting it?


Mar 19, 2017
Hi guys,
I would like to know how it is possible to remove a google account on my phone without deleting it.
I mean i got the account of my wife on my phone to be able to share a common calendar together, but i noticed that this ******* account shared also my contacts with her...
I would like to delete this account only on my phone, but keeping it on my wife's phone, is that possible? And how if yes?

Thanks in advance.
