Need advice for my bumble date

I (26M) met my (24F) date on bumble. we have been dating for around 3 months. went on 2 dates till date. She does a target based job in a small startup with alternate sundays holidays just like banks so bit busy. We used to chat , calls, video calls and whatsapp and being for the first time i followed a neutral approach.( she used to tease why i dont have a partner and to get one )used to complement her every now and then flirt. Few month back we were discussing about our past and i came to know about her ex who was with relationship with her for 10 years and she stills find it difficult to accept it. I didnt pay attention as moving on after 10 years is understandably painful and difficult to move on. But today while discussing how relationship works, she brought up the topic and says she continues to try to communicate with him ask him to keep in touch and can dump her anytime. his ex is clearly not interested anymore and doesnt give a positive msg as he is doing higher studies. she has difficulty to move on validates her 10 year time stamp. i tried to join on the clues and found her ex on social media. she follows her but he doest follow back. what should i do ? she insists that i was never in relationship so wouldnt understand it. I have a feeling for her. she is calm and gharelu girl. Has all the qualities i love, but at the same time feeling left out. i asked her why open bumble, she was silent. She called me 4 times i picked up the last time as it was her birthday and i couldnt make her worry this day. writing this msg at 5 a.m. now i cant stop thinking

TLDR: 3 months date says she tries to communicate to her ex (10 years relationship) and its very difficult to move on. her EX is not interested. lives quite lavish party style lifestyle. doesnt give any solid response to her( busy in higher studies) and doesnt even follow back on social platforms. i think she will eventually figure out but fear if he returns.
