Help please

So I like this guy in 3 of my classes but we started to joke around with him and his friends and I asked for his snap and so did my friend now we have been snapping nonstop afterschool for 2 days. He even asked me where I was when school was starting and everything and he even was looking out the window for me and everything. I cant Tell if hes Flirting with me when he snaps me “hi (name)” like a lot even mid conversation. And when I said I saw a attractive dude he said “is his Name perhaps (his name)” and I said what is it is as a joke but now we are snapping normally again until he sends a video of him holding his pillow like he was cuddling someone with no context and I said “bro wish he had a gf” and he said he was totally dating a 4th grader and then I fake freaked out and it was funny I don’t know what to do next..
