If a girl that knows I’m interested gets nervous or awkward when I’m around, is that a sure sign to not approach?

There is a girl that found out that I’m interested in her. She now avoids eye contact and when she sees me around she gets awkward and nervous. Months ago, I felt like she would hit on me often and send signals, now I guess I was wrong? Lol
