Chances are no matter what a Realtor is going to get paid. Why would you not one that has your best interest in the process. A Realtor representing seller is obligated to represent the seller and their best interest.
If you're the only buyer for the home and you're not located in an area where multiple offers are being submitted for homes, you can certainly represent yourself without an agent. To do this effectively, you should be aware of the protocol or procedures for making an offer and have purchased or prepared an offer with the assistance of an attorney or utilizing forms available to make an offer.
Based on the information in your question, the home in which you're interested is a short sale, isn't it? If this is the case, then you might have found it to be better to have an agent or Realtor familiar with short sales help you buy the home. In many cases, short sales are peculiar sales that require the expertise of both the listing agent and buyer's agent to obtain a successful close of escrow. Navigating a short sale without the assistance of a professional can be difficult, frustrating and, to be frank, ultimately not worth the wait in the eyes of many buyers.
If you submitted an offer with a contract prepared by an attorney or prepared by yourself with forms available through the stationery store, then you are representing yourself. However, if the listing agent prepared the forms for you to sign, you've just engaged the listing agent to be your agent in the transaction, and you will no longer be allowed to hire another agent for assistance. If this is the case, talk openly and frankly with the agent to discuss your expectations.

If the listing agent has already created the offer.....and you've signed it, then you have made this decision. That Realtor is also acting as YOUR Realtor. They have a duty to you as the buyer. But since they are representing both sides, their first responsibility is to the seller. If it's a normal sale...and things go smoothly, this is not necessarily a problem. But if you have not already gotten this far....I would highly recommend you find your own Realtor to write the offer for you, and represent you. The buyer's agent is paid for by the seller, so it costs you nothing....and they will only look out for your best interest.
