Firstly you need some serious help, you cannot try and assume someone elses identity and looks to try and manipulate your ex, thats so creepy, seriously you need to move on, be yourself and find someone that appreciate you are you are. Clearly its you your personality that he doesnt want and you cant change that. You need to move on and go back to looking like you.

Girl. Honey. Sugar. I’m saying all of this as gently as I can right now. You need to seek out actual, professional help. Even if you somehow manage to become twinsies with the other girl, he is not coming back, and the lengths to which you’re going to try anyway are honestly terrifying. He’s gone and out of your reach. Have a good cry about it, maybe get mad about it for a while, for sure seek out a paychiatrist, and move on.

this is really, really hard. but he didn't run away with her for her exact looks, and you with her look isn't what he's after. you will be so grateful to yourself in a year's time if you take time away, go out with your friends, get a little crazy, and move on for yourself. you don't need red hair to be beautiful

It's not just a "type"-thing. Whatever reasons he left you for her are his and could be any number of things. But the thing is - Changing your entire self to match whatever checklist you think he's running off of - It still won't change the fact that he did not want to pursue the relationship further with *you*. And that's allowed. People are allowed to decide they don't want to be with you for whatever reasons they have - Even nothing specific at all, and you do need to respect that. Honestly though, you deserve to be treated better ***by yourself*** instead of hopelessly chasing someone who doesn't return your affections. Agreeing with the previous commenters - You should definitely look for some sort of therapy to help understand and process that you can't make him want you, and that's okay. It'll be okay. You deserve to let yourself move on.

what you're missing: she's her own person, not a cheap knockof with apparently no individuality whatsoever. get a life. preferably your own one.

Authenticity? Seriously though, people are not "winnable" through such means, and if they were, they aren't worth winning. I'm frankly terrified for you and your well being, not your now-dead relationship.

are, are you like, okay, babes?

Obviously it's not just her looks that he was after. What you are doing is kinda creepy and almost stalker-ish.

That is the dumbest strategy to try the most desperate and futile maneuver there is. You need to move on and be yourself. You can't George Santos your way through life in the long-term.

Personality?
