I M23 was having crush on this cute girl F21, we didn’t talk much, just one time where I was asking her to remove her phone from the lat machine. We had lot of eye contact like some 10 seconds or more uninterrupted, kinda feeling awkward sometimes. I found out she also likes me how because one day when I was outside the gym door she came with her friend, and her friend was pursuading her to tell me something which I understood that she wants to propose me, but what happened was I felt nervous and went inside the gym, that whole time during gym she was staring at me like she wanna tell me something, but dumb me didn’t approach her, next day also same thing happened, and guys at gym noticed that and it became awkward, and she stopped coming to gym. She lives nearby to the gym, I saw her couple of days, with same stare as she wants me to approach, but I feel nervous to go and talk to her in public. I have started going outside his house to eat ice cream so that I could spot and talk to her but everytime I gets nervous after seeing her.
Tldr:
How do I approach her in public.
