Anyone listing their property for sale through a real estate brokerage would enter into an agreement that usually identifies the agent as the main contact source. So for a buyer to have direct contact with the owner is highly unusual.
There are a variety of other arrangements that include discounted services that leave the actual selling in the hands of the owner.
Your best course of action would likely be to be woring via a local real estate professional that will look out for your personal well being alone.......
I doubt that the realtor is preventing the sale of the property considering that is only way he gets paid!
Why not contact your favorite realtor and let a professional help you with this transaction.
Unfortunately the barriers to entry on pretty low for real estate agents. That means that almost anyone can bet an agent, and depending upon their level of commitment and training, many strange things are possible.
The key in any sale (IMHO) is the capability of the listing agent. Some listings should never have been taken, some listings taken will never be sold.
What does your agent tell you?
In some cases, the listing broker may get paid regard;less if the property sells or not, but that is very unusual. Same thing for a buyers agent, some do get paid regardless of if a home is bought or not, again very unusual
Are you working with an agent to represent you in the transaction. It does not cost you anythoing, give you added protection in the deal and can get you the answers you need.
I work as a buyers abgen and do offer rebates in some cases. Feel free to contact me directly if you currently do not have an agreeement in place with another broker

What actually concerns me more is that, from your question, it sounds like you do not have an Agent representing you, watching out for your best interrests and being your advocate.
In fact it sounds like the listing agent has created a dual agency and is trying to represent both you and the seller. There is nothing wrong with this, as long as you feel that you are being properly represented and protected by the single agent working for both sides.
It sounds like you do not feel this is the case.
It may be time for you to find your own agent.
