What should I do???

I choose to be anonymous for a few reasons but I'm in a tough situation. I'm 16 and at the beginning of this year I started being a thing with a boy whom I'd known since 7th grade. We had a class this year and we got to know each other better. Of course I'd always thought he was cute but now it was developing into a crush for sure. It was going good and around spring break things were getting a little weird between us and we stopped talking. I finally after two weeks asked him what was up with that and he said he didn't want a relationship. So we both agreed to be friends with benefits and not to catch feelings. (Of course I still had some feelings for him but as we started I was thinking I would just lose them and we could just be friends who did stuff together) Well I ended up losing my virginity to him and we've had sex multiple times and I just recently hungout with him again now that schools over. But I realized that I love him. I realized that he makes me feel at home. I don't know what was different from this time than the others but something definitely clicked. I don't know what I should do about this though. I feel like I can't tell him I love him because I'm afraid he doesn't feel the same or has any feelings because after all we agreed not too. But in the last three weeks he has acted a little bit more lovey dovey. He compliments me a lot and not just on my body. And he's called me baby a lot more than he ever did. And the way he acts when we hangout definitely confuses me. Could anyone help with what I should do??
