F18, First breakup. How do I feel?

This was my first relationship. We have been together for a little more than 4 months. It has been 17 days since I haven't seen him in person because we're on college winter break. And we've both been busy to call regularly so we've been texting and called a few times. Then, yesterday evening he texted me saying he has something to tell me about our relationship. And I considered the thought of breakup. So we called and he said he wanted to breakup. As my first reaction, I just laughed. I was his 13th relationship but he didn't feel like a playboy or didn't do things a playboy would do. I never felt like I was used before but now I do. On the call, he kept saying he felt our relationship was different than his others and felt it was special. He said his family and friends told him he looked genuinely happy. He said he felt a disconnect hence the breakup. I feel it is unfair to me. I don't know if I believe him because I don't know what is genuine and what is not anymore. He kept apologising that he had to do it over a call. And I am a little mad at him but kya karein ab. I don't feel particularly sad about it and I don't think I will cry. It is disappointing but I don't know how to feel. This is a very underwhelming first breakup experience.
