Is it normal that this happened

It has been 5 years since i met this girl we hanged out and i felt so damn sure she is the one cause i always had that feeling about her, I am a very popular person and i easily could have known someone else but i didn't want to I shut off myself and blocked every woman i used to talk to and i suddenly became so goddamn loyal.... I became less popular and i didn't mind I spent the last 5 years dealing with her bullshit her repetitive insults and the fact she changed in every single aspect of her personality, she became so cold and careless with me and trust me when i tell you i have dealt with more bullshit than anyone could handle I don't know what to do it breaks my heart to tell her that i can't stand it anymore
