My first heartbreak

I’m 17, I’ve been dating this girl for 4 years. We were long distance, I’m from California and she’s from Michigan, but we made it work. We were so in love. I had never had such a strong connection and bond with another person ever in my life. I’ve never had so much trust and love for someone ever. She was truly everything to me just as I was to her. Everything seemed perfect. Our parents approved of our relationship and we would fly out and spend a few weeks with each other every few months. Until last year, she had told me she lost feelings for me and we broke up. It lasted a few months, and she even made out with some dude, but he ended up being weird and she came crying to me about it and realized what she had lost. Not long after we got back together. A year later, the same thing happened. I had just spent the entire summer with her in Michigan, everything seemed perfect out of a fairy tale. It was the happiest I’d have ever been. I had even made the decision that once I graduated from high school I was going to go to school with her and we were going to finally break the distance and be together for good. Then, a few months when school started up for her (she’s in college) I noticed she was a little distant, and I felt like she was losing feelings again. Sure enough, a month ago on September 12 she sends me a voice message saying she really doesn’t feel anything. I was destroyed. We broke up that same night. We talked a little bit then decided that no contact was the best for us but we still kept talking to each other. A week later she talks about how she’s talking to this boy she really likes and they even made out. That really hurt but it wasn’t as bad as the first time. This boy also ended up being a weirdo and she again comes crying to me about what she lost and realizes how good I was and that she shouldn’t have used some random guy as a rebound but she was not going to get back with me because she still didn’t feel anything for me. Ever since that we had been texting, even flirting at times and we had booked a flight to see me in the winter right when I left for the summer and she said she still wanted to come and see me, but a few days ago she has been pretty quiet. now just a few hours ago she informed me that she thinks we should not ever contact each other again. She apparently found this new guy who she genuinely likes and she likes her back but they agreed not to date because she’s just not ready. And she also says she doesn’t even think of me anymore. I’m just absolutely devastated, I don’t know what to do I’m just so lost. I want her back more than anything but I’m afraid it’s really over this time. I want her to be the one so bad. We had such a beautiful relationship and I don’t know what happened. I really dont think any other pain tops this. My heart feels like it’s been ripped from my chest. I don’t know what to do and it would mean a lot to me if someone could give me some kind of advice or guidance.
