Showing property without realtor contract?

Contract ended with realtor, taking time off for holiday season. Also needed to decide on whether to re-sign with same realtor but to be honest, probably won’t. They reached out to say someone was interested in seeing my place and if I would show it. Now, we are without a realtor technically. Part of me feels it’s a trick to see if we signed with someone else or to keep one foot in the door with us. What would someone do in this situation?
