3 years and more confused than ever

Hey guys! So when I was a junior I started talking to this guy that lived about two hours away, we became really good friends but never really anything more. We would talk constantly (everyday basically), we’ve had fall outs where we didn’t talk for months but eventually we reconnected. I’ve always had feelings for him and kinda wanted more. But every time I even heard he was talking to a new girl or with someone it didn’t last very long, I guess you could say he just isn’t the relationship type. This year we both went to college at the same school, I was living in an apartment with my male cousin, and the two of them became very close. So in turn I was spending a lot of time with him! It was great, I even became friends with one of his close friends (a guy). But, one night when we were all sitting around his friend said “Hey you should add me on Snapchat!” And you could just see how mad this guy got as he said “She listens to my bullshit 24/7 I don’t think she wants to listen to yours too”. Now I thought that was really weird!! Like he’s really getting jealous rn? So I just ignored it. There’s so much to our relationship to explain but basically he says I’m like his best friend, my thumb print is on his phone, he took my virginity in November, but he’ll never talk to me about girls, sends mixed signals like no tomorrow, and never really flirts or makes insane effort. I don’t wanna lose my best friend but I also don’t want to be strung around. I really feel like he could see something real with us but just wants to be a hoe and enjoy his young years. What should I do??
