You can do two things:
 * 1) Block him from your Gmail account.
 * 2) Close down your Gmail account, get a new one, and do not tell him what the new account is.

To block someone on Gmail, click on the gear symbol in the upper right, then pick "Settings". Click on the "Filters and Blocked Addresses" tab. Click on "Create a new filter". Put Kevin's email address in the "From" box, then click on "Create filter with this search" in the bottom corner. Put a check mark in the "Delete it" box, then click on the "Create filter" button.
