Finding your behalf

I've been of the opinion that I don't want to marry and will enjoy life single. Turned 28 this year and for some reasons, my thoughts and perceptions changed and decided to give it a shot. Installed a matrimony app and didn't find much things happening there until I found a girl whom I thought I would give a try. I requested a match which got accepted very soon. Fast forward, it's been 2 months since we whastapped each other. The only thing bothering me is that she's working in audit and says that she's too busy for texts, calls etc. And over the course of this 2 months period, we only managed to call each other thrice(including 1 video call). I had asked her to atleast try to call me but she's too busy/ not feeling well/ tired etc. I really had feelings for her initially, but even after multiple attempts, she still keeps me waiting, I feel I'm slowly losing it and have reached a stage where i don't feel anything. What should I do? P.S. we live in different time zones with a difference of 1.5 hours and by the time I'm back from gym, it'll be 11-11:30 pm her side. I try to have food and everything very quickly and make time for her everyday, only to be disappointed most days. And most of her texts are scattered, with time gaps ranging from 10-16 hours at times. She tells me she's too exhausted and has no energy for anything but I am cent percent sure that she is using phone for insta, twitter etc even when my chats are waiting.
