I am devastated

I am a 23M my gf broke up with me a couple days ago, it was very bad. I literally slept an hour in the last 48 hours ate nothing. I was upset about the way it happened, I mean I loved her so much, I met her family we’ve been going out a lot and having a good time. and then suddenly I called her to check on her I was telling her you don’t feel like your self lately, If U have any problem U wanna talk about I am here, If I did something that made you upset just say it. she said no you didn’t do anything you’re fine, you’re great. and then I asked her about us, I said what am I to you now, what’s our next step, and then she said that she wanted to talk to me about this face to face, but it’s fine we can discuss it on the phone, and she literally said logically If I am using my brain you’re the most amazing guy I’ve ever met, and I should stuck with you, I never met someone like you, you left something in me, but I am sorry I feel nothing I have no feelings for you, and then she started crying on the phone for like 30 minutes, saying you’re fine please don’t be upset it’s not about you it’s about me, I really wanted to have feelings for you but I couldn’t. And after that 30 minutes of crying she hung up, and I am devastated since then, I mean an hour before this call things were good. this feels like it came out of nowhere should I contact her or just move on
