Finally spoke with my gym crush

This story goes back to a few months ago, I notice this attractive girl and made eye contact a few times. 1ST ENCOUNTER- So one day I got the courage to speak to her, asked where she got these unique leggings with a wolf logo on so I can “buy a pair for my mom” she really engaged with me about the product. I then told her I loved her style and cracked a smile on her then went on of my day. 2ND ENCOUNTER- I really fumbled this one… but weeks go by of just eye glances to each other, but get a chance to talk to her again simple greetings to each other but I said this line “How is always that I’m here you’re here” tried to go with some kind of banter but was stupid she then said “it be like that sometimes just happens” gave her a smile and fist pump and went about our days. Fast forward to today 3RD ENCOUNTER- after weeks glances a lil awkwardness, she comes to some nearby machines where I’m at. Was weird because seemed like she avoided me or didn’t notice me. But I went to up to her and stuck up some light conversation. She did engage but nothing like the first encounter… tried to make it short as possible, let me know if you need more info to help a foo out.

Should I try to be flirty a little more next time, if so any recommendations? Or is it over for your bro?
