I need help fixing a problem.

I let this guy named Nicholas borrow my phone and he saw a secret website in my internet pages. I need him to forget about the website because it’s a secret. Also, I ended up becoming friends with him and “snitched” on another guy named Ronny somehow about something that had to do with Nicholas . I heard someone say snitches get stitches from the bathroom upstairs and I think Ronny, in my head, making me worried that snitches get stitches. I did research on what snitches get stitches beaches I’m a little scared.
