The main post sounds like you have something you want to hide.

It needs an update to clarify this.

The first thing I thought is you have sex toys and you don't want this person finding them and telling your family - as this person is a snooping one.

When I read about the fridge I start thinking you have something weird there.

Anyway, it's your apartment, get control over it. Seems u let some other people force you to do something you are not comfortable with.
