It's hard for any of us to give a reason why, we are just host like you,
One of the most annoying things for me is the lack of communication from airbnb Im sure there is a better way to do things rather than just shutting people down,
Why dont they ask a questions first, It;s like you are guilty until you prove you are innocent.
This is what I do, I always print off the guest information as soon as I can and thats usually within the hour, then I add the guest details and phone number to a Whats app group then you can always contact them direct.
All you can do is get yourself listed on other sites as @Mike-And-Jane0 mentioned,
VRBO, BOOKING.COM, TRIPADVISOR and AGODA,
Open another airbnb account in your partners name, using a different phone number and email,
