So what you are saying is the best solution to this problem is to do nothing?
If you don't want to do an RBF or CPFP transaction, then all you can do is wait. The Bitcoin will either be "returned" or the transaction will confirm and the recipient will receive the Bitcoin.
How long is eventually when should i expect to be able to use these coins again?
It usually takes 2-3 days for a transaction to be "forgotten" by the network. Whether it will confirm in that time is unknown.
