Should I do it?

I was seeing my best friend cousin and for some reason he stop contacting me. Well she told me that he thought over our situation and notice how it can be a bad idea to be with me since i’m her best friend. She say he still likes me and all, but he’s just unsure. In a way I was thinking about moving on, but she been telling me to just try to communicate with him and give it one more try. Can you help me with this?
