what should I do in this situation? Share your opinions

Good afternoon, dear users. The fact is that I was dating a girl (as I thought at the time), she lives in Turkey, everything was going well with us, and at some point she started contacting me less and less often, it was very important for me to keep in touch with her because she it supports in me the feelings that I was experiencing at that moment, and oh, God, how wonderful it was (sorry, I'm writing this through tears). I loved her very much and I still love her, but she didn't understand this and gave me false hopes for a bright future with her. She just didn't give it any meaning. She just trampled my feelings into such an abyss of despair that I was ready to shoot myself, but at the same time I flattered myself that she would finally come to her senses. In the end, she just played on my feelings and then the day comes when she stopped contacting me, quit her job and started hanging out with friends, and at one point she called me via video link with her friends (I understand they had a bachelorette party) and just started bullying me (I do not know Turkish, but I understood it because they were making faces and they twisted their finger at my temple, they did it after the girl told me) but it was a blow to me that she was the one who said those cherished words that I had been waiting for "I love you" in my native language. all the negative emotions immediately evaporated, as if they had never existed. The day after the call, I asked her, "Have you learned a word in X language)? She answered yes. after that, she didn't respond for 3-4 days and I was very worried for her that she was in trouble or in the hospital (she has vision problems). after I received a positive response, I asked her about that call and the words she said, she forgot and replied, "I said it with the help of an interpreter," and we all stopped communicating with her, but after 3 months she wrote to me that she wanted to come back without even apologizing for her behavior, and everything started very well, too. Literally After two days, she didn't answer me again, and I somehow let it go, but I still couldn't calm my feelings, and I wondered why she did this to me and why it was all for. Two months later, she wrote to me again saying that I miss her and that she doesn't need money and the like, she just needs love because I loved her. And then she adds that I'm the only one she needs. dear users, please help me, thank you for reading this post, I think it will be deleted, but the attempt is not torture. I want to fly back to Turkey to get married and pick her up from there. What should I do in this situation? What should I do? Should I trust her?
