Is it normal to still love my ex after 2 years?

My ex and I began dating in 2011 (freshman year of high school), we were high school sweethearts we were each others first. We stayed together until late 2015. My parents got divorced and I had to move 2 hrs away to stay at my grandparents. Also was dealing with some health issues (low bp, fainting ect.) which put a strain on the relationship. While I was there the commute became an issue since he at the time didn't drive and I didn't as well. We broke up ( he broke up with me), I had a house fire at grandparents few months later, my mom moved to Australia and I ended up moving back to my hometown (2016). We became close again when I moved back and got my own place (I was able to drive & he got his license too) we hooked up all the time but never "dated" again. I was hanging out with his family as if they were my own. He'd come over to my place and his mom and I would hang out together too all the time. I celebrated Easter & my bday with them since I had no connection with the rest of my family & my mom was in AU. In August he became very distant and weird with me and pushed me away. He blocked my phone number- than unblocked me...He made it clear that he wasn't seeing anyone or talking to anyone but couldn't be with me. The fact that I could possibly move to AU was brought up when I first came back to town and he told me to go and be with my mom. ( my mom wanted me to go live out with her in Australia & later on in the year purchased me a ticket to leave in November 2016) I left at the end of November. November he blocked me on Snapchat. December he unfollowed me on instagram. We still messaged here and there but that's it. Just a few months ago he blocked me on instagram (simply put he "didn't want to see my posts" I reached out to him because living with my moms new husband in Australia was absolutely horrible. He didn't answer. Week later I made a post saying how hurt I was ect. But never mentioning his name). His mom and I still spoke and are still speaking to this day, but he has made it clear to her that he wants nothing to do with me. My visa expires in a month so I'm coming back and even me going to the same gym with him ( we both go to the same gym ) will be an issue... he doesn't want his mom & I talking either anymore - she's cried over the fact that she sees me as her family and she's being put in a difficult position. Which I completely understand. She says that I'm his "Kryptonite" that's why he can't see me. But his mom made it clear that yes she wishes things were different but I should move on - for me. Being in Australia I Found no one attractive and can only think about him. He hasn't seen or dated anyone this whole time either. I still love the kid I don't know what to do or how to get over him. What should I do...
