He was talking about me...but what does it MEAN???

Me and this guy have been talking a lot lately. We chat for hours together online, and we text a lot even during cl, and study together too. When we are actually among other friends though, we are pretty platonic, even though we flirt a lot online and when we study. Recently, his friends brought it up to my friend how we talk online for hours together, and how this guy doesn't even do his hw sometimes so that he can talk to me. Of course, there is no way they can know this unless this guy told them. I guess he also told them we talk a lot at school and study together. They kept pushing it to my friend how I MUST like him if I talk to him so much. I'm not sure what that means...he acts platonic in front of our friends, but then is telling them we talk a lot anyways? Does he have a thing for me maybe?? And why would I be the one who likes him if we are BOTH doing the talking and flirting. Regardless though, I actually really like him haha
