How Do You Let Go of Someone You Never Really Had?

In my first job i have seen a girl she was my collegue. i usually not talk with girls, but my friend used to talk with girls so i used to manage to talk. after 1 month i talked with a girl crush who i got attracted and loved most because of her beauty like hi how was the work going then i used to sit in my cubical and watch her. she used to talk with all boys who are better than me and they all use to try her and flirt with her. she used to like the attention from boys she is getting. on christmas with help of my friend me and my crush we had a photo together. this is like used to go on in my office. so i asked her insta id. she gave it. i used to send crush reels to her she used to like it but did not send any kind of reels to me.

One day i asked her friend where is she. she said do you like her. and i said i dont know. then she immediaetly ran to her and said he likes you. her friend once called me and teased me like my crush is calling me. when i went to her she said no. then i listen some words from my collegue that she said to her why are calling him, if starts following and tease me. then i felt very sad i ignored my crush stopped sending reels i went to work from home. then it was last working days in my office. i getting a regret i not talked with her even for 5min, my friend talked with her for me for an hour i never talked. then her friend came to me and started talking with me i also talked with her friend then she came i said openly i have tried you but you have not fallen take it as chill. then she agreed me then talked with me for a while and went for a juice break with her friend while leaving office

Next day is my last working day. her friend call her. i talked with her in a comic way she laughed and my fellow collegue who used to try her and also his last working day with me. then i said be in touch in insta and she said for sure and byee. but i am unable to forget her after leaving comapany. i used to send and unsend reels on insta. after 1 month she reacted to the reel i send her, she said "hi". then i texted "hi". then i used to flirt with her in chat she reacted positively. then we even chatted for continous 6hrs. but i asked her to meet. then she said okay! like this going on for a week. then again i asked her she said i will ask my friend get to know. then she stopped replying to me for 3 days. then i contacted her friend to get know what happend about meet did she(my crush) told to you and i opened up with her about my full one sided love for a 2hrs. then she said ok i get to know about meet and said i will not say this to her(my crush).

Then here it is BIG SHOCK!. after the call ends with my crush friend for a while. my crush blocked me on insta. her friend also blocked me. my heart totally broken. i sent to my crush birthday wish on whatsapp. she did not even replyy. then after a 1 month i have sent her insta reels in whatsapp like why did you do like this. she blocked me on whatsapp. after 20 days one of my collegue coincidently meet her and he called me and said forget her(my crush). then i used to go to her office to see her i have seen her at a distance but never dared to meet her after the block. after few days she got assigned to work from home, i dont know her home. then again after that i used to send her money whenever i feel about her. then after 1 month she blocked me on moneyapp also. Then i felt enough. Still i am feeling heartbreak still i am stalking her insta through my friends account. how to recover from this pain please help me guysss!!
