Search Results: flirt with me one day then ignores me the next

I have a huge crush on this one guy, we're friendly and we like to hang out and talk. Lately, he seems a lot more flirty, such as he maintains way more eye contact and stares at me much more frequently. My friends' notes he becomes much more nervous when we talk such as avoiding eye contact, nervous smiling. All of my friends are always asking me if there's something between me and this kid, and even the teachers say so too. He's a very nice yet sort of shy guy and he's average looking although I know of two other girls who like him as well. He loves teasing me and makes it a usual conversation starter. He initiates most of the conversations and usually seeks me out whenever he can. Although, there are sometimes where he completely ignores me and/or stares at me but doesn't say anything, however, he usually does ends up talking to me in the end. We're in different classes but he usually waits for me after class and/or walks with me to my next class. I have a gut feeling he likes me, however, I do feel like he is a flirt and social media makes me a lot more apprehensive. He comments really flirty emojis on these few girl's pages but they all have two things in common, they're way out of his league and/or they have boyfriends. He also has a lot of female friends too. But he doesn't completely ignore me either, he sends me these weird posts every 3-5 days but what irritates me is that when I respond he could sometimes continue the conversation but then sometimes doesn't. He also views my stories almost religiously. So what I'm asking is... does this guy really like me? Is he playing games? (Note: I try not to make it obvious I like him and sometimes play hard to get/ be mean to him) . Could he know I like him and be leading me on?
Please help me out!
