Konkret: Wie kann ich mein monatliches ABO für ein paar Monate pausieren.

I’ll ask an Adobe employee to move this to Account, Payment & Plan for you. 

• Stock Credit Packs are good for 1 year from the date of purchase.

• Month-to-Month plans can be stopped at anytime without penalty. 
   
• If you have an Annual contract, you’ll likely have to cancel, pay an early termination fee, then resubscribe later.
   
• Log-in below & click Manage Plan.

• Adobe Subscription & Cancellation terms:

Hope that helps. 

You can make inquiries by contacting customer support via chat or phone during business hours.
However, while there is a way to cancel your subscription, there is no option to temporarily pause it.
Canceling the subscription will result in the loss of any remaining credits, so you should use them up beforehand.
