What’s wrong with him?

So recently I got over a guy who ended up breaking my heart because I heard he might end up with a girl who wasn’t me. He was my second heartbreak but this one hurt way more since I wait for him about 4 years now and I decided to give up on him since I have no chances with this guy. Not to even forget he is really popular with the girls as well. So after I got over him it’s been a couple of weeks since he finally started approaching me and started a conversation with me other than I doing so. But during those 4 years I can tell I wasn’t his full attention so didn’t bother me that much, but what did was that he hardly talked to me. Till a couple months before I was heartbroken and gave up on him I finally had a class with him. Which was even harder 😖. So I started noticing that he was looking at me intensely so I thought that was weird. Even my teacher started noticing that she ended up making me sit next to him for the full quarter which was a struggle for my heart 😣. Then we started talking more often and also got to know each other better than I thought I could. We even had to do two poems we had to work with and they were romantic poems from my English teacher. So it turns out she was being Cupid all along 🤦‍♀️. Now that it’s a new quarter we no longer sit next to each other but I been noticing that he’s been jealous since I hug mostly everyone(I know it’s weird but I love hugs) including guys . And he doesn’t really know y situation with my family since I don’t have good ones but he always asks if I am okay since it’s like he knows! But I don’t even tell him I am I just hide it with a smile, but it’s like he knows all the time. So I don’t even know what to do should I try again? or should I just continue finding my new way of finding happiness with someone else?
