the answer is no. no no one can steal or take away your manifestation.

why is that?

because YOU create your OWN reality, you can ONLY create your own reality- you cannot create for someone else, everything that happens- is your own creation/manifestation.

but- think you are talking about something else and i wish to explain something to you which might help you understand more

first and foremost i think you have to understand that EVERYTHING in your life is a manifestation- literally every single thing you experience is a manifestation- more specifically- your own manifestation.

so

everything that is happening in your reality- concerning that person- is done by you

you cannot create or manifest for someone else- that person or anyone for that matter- what you are doing is creating your reality based on the beliefs you hold and the thoughts you are thinking- and subsequently that person and your whole world is manifesting according to that- so if you believe that your spiritual connection with her is what is causing her to replicate your visualizations in her real life- that is what you are going to get- you have created that reality for yourself

but that also means, if you now are starting to believe that she- not knowing this love you are sending her way is from YOU- a person she does not know- and another person will come and present themselves and she will go on to be with that other person- you will create THAT reality for yourself

you cannot feel for someone else, you cannot make someone else feel something because you are 'sending' vibrations to them- you can however make yourself believe that you are doing this- and you will have a reality that will mirror this belief back to you- she has nothing to do with this- because she is creating her own reality- one that you cannot create for her as we all create our own reality

by the way just a question to you- you say you met her and knew she was the one- but if you have met- why dont you just add her on social media and start talking to her? instead of sending these vibrations you talk about- isnt it better to just start talking (as friends- maybe better to wait until you present yourself as her spiritually connected heavenly sent true soulmate twin flame lover)

that way you would have actual contact and you would find out if she really is that special someone- because what you are doing right now is literally planning a move without even having a chat? that seems like quite a radical decision- if she truly is your soulmate and you belong together- believe me you will be together without you drastically changing your entire life- because if she is not the one- you have not only wasted time by worrying about her being with someone else that stole your vibrational love- you are also now in another city, a city with a woman that is not your soulmate and your gonna be like ok and now what lol

take it easy- if it belongs to you it will come and you will not be able to avoid it- try talking first and getting to know her better and i would start making plans after that only

hi, @Januaryfeelings gave a great answer. ijust want to add some things.

no one can steal your feelings, your desires or what you want. these are yours. but when you ask/believe someone can steal something from you, then it's like you ask the univers to do that same thing. it means you have a fear in you that it might happen. now, im not saying that it can't happen and that this girl cant be with someone else. im seperating her from you. and saying that you cant lose the feelings and desires for a relationship that you want, and it dose'nt have to be with this girl.when you are ready it will happen.
so, even though you want sepcificly her now, you said you dont feel ready to make any action. and an inspired action is part of the manifestation prosses. so yes, she could be with someone else, but it doesn't mean that that someone stole her from you. first of all - she never was "yours" she belongs to no one .just like no one can steal you! secondly, you! BELIEVE you aren't ready so it is only logical that you cant be together acording to your belife system, not just hers. but you can change that. and last thing - trust the univers to give you what is a match to you. no one can take or steal what doesn't belong to you. be peacful and trust.

be jentle with your prosses and with your way to readyness and don't push your self to hard from fear that something will be taken from you. that can never happen. trust the univers and yourself.

Yes, of course- people can come and rob you blind, take every last thing that was ever good in your life, if you really believe they can. That's how powerful you are.

You see, you are not inherently a physical human living a physical life- you are a blob of energy floating in a neverending nebulous mist. You took the shape of a physical human leading a physical life- including the types of events that you may experience- and that shape you take is fundamentally determined by what you expect will happen. On a big scale, you expect to be human- poof, you are. On a smaller scale, you expect to be drained of energy and hung out to dry- poof, you are. The point to notice is that you can also stop believing that, and start believing that only good things will happen to you.

How you do this is use your imagination in whatever way makes you feel good. So if you feel people draining your energy, grab them, and throw them out of an imaginary window until you feel the energy drain has stopped. If you feel the woman of your dreams is falling for someone who is completely wrong for her because you're not ready for her yet- imagine yourself being ready, right now, and being with her. Do this a lot- as in all day every day (at least a couple minutes every couple of hours). Use your imagination to shift your energy, and observe the results in your real life. Then you can use your power to help yourself.
