Could you all tell me if my decision was right?

I met this woman she was, adorable, cute and fun to talk to, and I liked her so much we just kissed. And it was obvious that we were attracted to each other but I couldn't help that she was married and I didn't wanna interfere with that and she said the L word to me so I decided to break up with her I didn't like doing this to another's man wife even if he didn't know me. Am I wrong?
