Got ditched for taking efforts for her

So I met this girl and she was cute and we were talking and she used to say she was like what's so special about me and all and would feel insecure but she is really beautiful many tried to hit on her still she felt insecure so delusional me who is so dumb who was into her soo much I made a 30mins vedio of talking how much special see his how good she is how her smile is how her character is and all and wrote a letter with a poem telling how wonderful she is just for her to make her feel special at the end she just said I don't want you to doo all this I hate youu....

I don't know I was just being nice wanted to take efforts what is wrong with women they say men don't take efforts if the do they do this...the words she said hit me so hard it took me hours to process it still the words which she told hurts me a lot

It's better too stay single after all this shitt I'm afraid to even talk to any girl or to take Any efforts
