Should I Pursue or not engage?

This girl I talked to is always giggly, stuttering and blushing whenever we talk and always has full attention. We ask each other questions and have a great time but when I asked if she wanted to talk outside of the gym which is where we talk and she said next time I see her stop by and talk to her. She didn’t give her number or social media but I like her and don’t know what I should do. Any advice? Should I pursue her?
