Мене кинула дівчина( втратила почуття)

It all started very beautifully, this is our first relationship of 17, both are interested in each other, our views were very similar to relationships (family, living together, values, etc.), we met for half a year, we were both mega comfortable together, each meeting was incredible because we even had the same sense of humor, we could laugh at those things that seemed funny to both of us, supported each other in difficult moments, discussed moments, when something happened in our relationship to better understand who was comfortable, etc., we were already planning even to study in the same country together, and everything was going for it, but during all the relationship I noticed that she was never the first to hug me, never almost, and in kisses I was always the initiator, which seemed strange, because she told me every day that she loved me very much, missed me and what even at the beginning said that she was very tactile, which strained me even more why it was so, but I, because this is the first relationship where I really loved a girl very much, I was ready to do everything for her sake, to come at any moment when something happened, to support, calm down, gave incredible care and love, because I felt from the beginning - This is her, this is the same one with which everything coincides with me she loves me and I love her, because even at the beginning of communication she was constantly the first to write to me and asked how I was, and then when I decided to confess my feelings for her, she said that it was mutual, and she wanted to say it while still walking, and I thought that this does not happen, because nowadays it is rare to find such a girl who will love you so sincerely just like that and so everything continued until our half-year, we celebrated it perfectly because we both understood that we are exactly the person with whom we want to live until the end of our lives, because there were no reasons for this to happen, we didn't even have quarrels. never.

And after we celebrated this day, she gave me from the bottom of her heart the same gift that I dreamed of from the very beginning of the relationship (I talked about it once), but the more valuable thing for me was that she made a gift where we were drawn together, drew with her own hands and made as if a frame that I could put on the table, and I was incredibly happy because I was really so lucky with this person,

But one day she tells me that I still want to be alone to rest from everyone, because I'm tired, and I said okay, I understand everything, I asked if I needed to listen, if something happened, but I said that everything was okay, (Our agreement was that we immediately tell our partner, or something is wrong in the relationship) and she tells me the next day to meet without explaining anything I went to meet her, and at the meeting she sat on the bench, hugging and sitting down to her, she tells me that I have not had feelings for you for a long time, I tried to make them appear, but nothing happened like that, I sincerely believed that I could feel something for you, I could not say anything after these words, she did not even look into my eyes when she said it and as it turned out, after 1-2 weeks, she didn't feel anything for me after the start of the relationship, and she just thought that it would pass and everything would be fine, she wrote how she loved me, etc., introduced me to the family, told me the big little things of her life, which only I knew about, and that's how she just abandoned me in one day, and all our fun moments together, all hugs, words, kisses, etc., turned out to be just pure lies and simulations on her part.

I would like to ask you, was it possible to change something here, and is it normal how she acted?
