Is this normal?

So a while back I dated this guy. I honestly just thought we were gonna end up friends because he really liked me but I didn’t like him. Slowly but surely I started falling for him. I told him about my feelings for him and we were so happy. Dating. Everything was so balanced and came naturally. Nothing was forced. It was unlike any other relationship I’d ever had. We started having sex and he truly made me feel intimacy. He showed me what it was to actually make love to someone. Passionately and intensely. My own ex who I lasted years with never made me feel that way. But a man of a couple of months did. But anyways, turns out we wanted different things and unfortunately things ended between us. It’s been about half a year and I still can’t get over him. There’s days where I miss him so intensely that it feels like I need him. I know I don’t though! And there’s nights where I masterbate but as soon as I’m done I’ll start to cry because I’ll think of his face and his voice. The way he made me feel even if we weren’t having sex. If it was just a small kiss. The butterflies. I’ll just want to curl up into a ball and cry. Is that normal? I’ve been so incredibly sad ever since.
