How to semi block someone on Facebook.?

[Haleigh]

I have a huge issue on Facebook. My bio father has been stealing my pictures, stalking my husband and myself, and now he is threatening to try and get custody of my unborn baby. I had a picture from my college sorority days that I forgot about. It was me in a skimpy bikini. He stole it, posted it on his wall with a post saying "no longer hiding my trophy wife". I know it's me because it was at the college swimming pool, and there's an APhi on my top. Plus he doesn't date white women, only Chinese women. I've asked him to remove it, but he didn't so I had to go ask Facebook to remove my stolen picture.

So I don't want to fully block him because I want to make sure he doesn't have any pictures of me or my child. If I block him, I know I won't be able to check on him to make sure he doesn't have any more pictures. Is there any way I can do that? I don't want him to talk to me, nor steal my pictures.
