Help w cloud sharing

[Jmay76]

i had an old client that went sour still in my shared photo cloud stream list. He originally invited and sent me photos and never unsubscribed me because the photos have been sitting there. Today I saw the shared file and decided to click on it. To my horror I've been adding share vs delete recently. How I don't know. It showed 63 photos shared. I panicked and turned off iCloud sharing. Then I turned it back on and unsubscribed him. Are my photos still shared? I assume he didn't download or make copies. Please settle my nerves! If not, is there a way to delete them now since I forjot to begore shutting off the cloud? Of course now I think he's seen all my photos not just the ones I shared. Help!!
