How do I undo something that I did?

Okay here it goes. A month ago I met this doc in a famous hospital in Chennai. My dad was getting his finger stitched. He is this assistant doc who helped the senior doc with the stitching. I had to be there for 2 days initially. I thought his voice was attractive but didn't give much thought to it. I noticed he kept giving me glances everytime and even when I visited for follow ups. He literally kept turning back to look at me whenever I spoke to his senior. Once my dad asked me to call him to check for appointment. I asked if the senior doc is available, he said "you can come anytime you wanted and even now you can come" in a laughing tone. It got me curious. I didn't do anything about it at first but I got lil creepy yesterday and found his IG. I thought to myself "okay I'm gonna be a Sarabi and find out if he's my Mufasa" and sent that request with my eyes closed and turned my data off and threw my phone away (Acho perumale vekka vekkama varuthey) After an hour or so, when I checked my phone, I saw that he didn't accept my request, instead he has sent me a request back. I didn't think much of it. Probably he wanted to confirm or he doesn't remember me at all as he's a doc afterall and he'll be meeting lot of people etc. Okay I accepted. 30 minutes later I couldn't find his account at all. That man blocked me lol. That's no Mufasa, that's Taka..my heart screamed. That did sting a bit and bruised my ego. But meh it was just a trial. Again after an hour or so, he unblocked me but didn't cancel my request. So I simply cancelled it and my bruised ego blocked him. Why do I have to do this? I so want to go back in time. It's embarrassing.
