I empathize with your situation. I pray to Allah to fulfill your cherished dream - provided it is good for you.
I know you are in mad love for this girl in spite of the fact that she has no liking for you. How often we come across situations in life that we find something attractive and want it so badly and yet it turns out not so good after all. That is why the best advice I can give you is to pray Salatul al-Istikharah. If you read the Du'a of Istikharah carefully, it says: O Allah, if in Your wisdom and knowledge, this thing is good for me in my worldly life and the life hereafter, then facilitate it for me. If, on the other hand, it is not good for me in my earthly life and the life after, then move me away from it and move it away from me, and facilitate what is right for me.
For details on Salatul istikharah, please refer to the answer linked below:
