So long story short, i have this friend lets call her PP. We had been friends for a many many years and fwb without sex (just everything else) for a few months too. Friends who could talk about anything and for hours

After that i got into a relationship so we just stayed friends who would yes flirt (i admit) at times. Yet i had to keep her a secret from my gf so wouldnt message PP all the time and only when alone and not let her text me randomly etc. Then, she got into a relationship of her own which im guessing is serious because she was looking for a serious thing last i spoke to her and then told me very rudely that she doesnt want anything to do with me.

She didnt remove me on any socials so i still commented on her story a month or so later and she blocked me on insta but not whatsapp.

I know some will say i should let her go but i miss her and i just want to talk to her as friends only but dont know whats the best way to approach her, or an excuse to approach her. Im not single so im not looking for anything and i know she isnt either but please help.
