let it lie

to take no action about something (from Cambridge Dictionary)

Instead of going to the police they let things lie for a couple of months.
Sally: You can't take it back.
Harry: Why?
Sally: Because it's already out there.
Harry: Oh, Jez. what are we supposed to do? Call a corps, it's already out there.
Sally: Just..let it..lie. OK?
Harry: OK! Let it lie...
