To answer your question, yes, you can go to a different Realtor.

Make sure the realtor you select WANTS to work with buyers. Some agents WILL work with buyers. There is a big difference.
Bottom line you have to work with someone you feel most comfortable with. The agent who knows you, may have an expectation that you will work with him/her. If you do not feel they are the right fit for you, you should let them know ASAP if do decide to work with another agent.
Best of Luck to You!!
