Did I fail to build a bond in relationship?

There was a girl who liked me for a long time. I liked her too and we got closer. After some time her friends started telling things and it sounded like she is not sure of me or something. We went out and then she ended things. I wonder if i failed to build a better bond and trust in relationship. We were still nervous around each other, we run out of things to say sometimes. I feel like I screwed up.
