It is up to the seller to decide what to do
They should not really relist until your sale is sorted
The seller could send a cancellation request for you to agree too
Most would not do that they would open a non payment dispute and went closed you get a non payment strike on your account
When you bid and do not complete the purchase it costs a seller time and money
If the seller cancels the sale the item will show as unpaid on your ebay page for a while due to ebays programming
It will eventually disappear
