OP only you know about the country you are living. Please consider the very worst case scenario here and safeguard yourself against it. Consider leaving with the smallest of bags as soon as possible - most things are completely replaceable - and take a flight to anywhere in Europe. You, travelling solo, are highly likely to be able to get a flight straight away.
You are in danger now and waiting a week on the chance that he goes away to work just to get all your possessions packed is incredibly risky. You are giving him a week to harm you more, report you to the authorities and have you taken into custody/sectioning and getting your passport removed/freezing your access to money.
He may anticipate you leaving, given that you are understandably avoiding him, and it’ll be obvious to him that you will be planning to leave for good when he is away so may already have cancelled or rescheduled.
The window of opportunity you have for leaving may already be greatly reduced.
Please consider this and simply leave with the absolute essentials.
Do you have joint accounts? Do you have money not monitored by him? Is it safer to not buy a flight out of there in advance and just get to the airport and buy once you get there.
Is your phone tracked ? Even an innocent app like Life360? Can he see where you are at all times?
Hope you’re ok OP. Don’t let him talk you around here.
