Should i try to fix my friendship or move on?

[Posls]

So i met this girl who was my first love in middle school, we were best friends and eventually we started to like each other but i never made a move bc im a pussy, in high school i stopped talking to her and she got into a relationship with a guy so i legit got over her.
Now we met again at university last year and it was fine i actually didn't feel anything for her and it was a good friendship again, everything was good until this year i started to have feelings for her again out of nowhere but i didn't think it would be a good idea to make a move on her so i basically started to push her away from me, she asked me if there was something wrong or why i was mad but i didn't really answer so i went for almost a month ignoring her thinking those feelings would fade away but they only got worse i even feel jelous of my own friends for talking to her. So now idk what the fuck should i do, i have been trying to fix my friendship with her but i can't even look her in the eyes and its not the same as before or i could try to move on from her. I also can't talk this shit with my friends because it would only make it more weird.
