Is this guy gay and possibly likes me?

Ok so it's my freshman year in highschool. I am a gay male that doesn't have much luck with finding someone to date. Well this new girl Rebecca came to our school and I had to help her around school naturally we became friends and stuff and I like this on guy but for his and nothing else and I told her everything that has happend before with him bit I also want a guy to like for his person and I would date him after I got to know him. Well I told er this and she is like what about Devin? He's a guy from our math cl and he's kinda cute and she's like I think he's gay and maybe likes you. I talked to Devin one time before Rebecca came and he is nice. Well she asks him if he likes boys or girls on a note and other ppl read it so he doesn't answer. Well after we got back from lunch they somehow got to talk in private and she asks that and he asks if she is friends with me (kinda odd I came to his mind isn't it?) well and she was like yes why? And she says he looked back at me with a "flirty" smile as she says and doesn't say anything and then before we leave he tells her he isn't that way and if I was wanting to know to tell me he would still be friends and talk to me! And then that day on the bus he is infront of her and turns around and says hi and she says hi and then he turns around again and asks if she has my number she says yea and then it's his stop so he gets off. Then the next day nothing happend. Now today she said he said in math he was gonna talk to me did nt say in a good way or bad way. Is there a possiblity he likes me? I mean I would have to get to know him before we dated he's cute and nice from what I can tell. Btw rebcca said before all this she thought he was cause she said he's looked at me in math before and had that "flirty" smile/look. I am trying not to have a major crush on a another stright giy this year and I don't wanna waste me time so what do you think? Btw he was at lunch with this ugly tall red headed guy and walked the circle with him and in the hallway back from lunch That couldn't possibly be his boyfriend? That would be my luck a cute guy likes me but is taken
