Does he like me? I really need help on this one! Only experienced answers!?

I am 13 years old and I just got out of 7th grade. I have liked this guy who is in 8th grade for a long time and I think I still have feelings for him. We joke around on the bus and we share a lot of interests like history, reading, and science. We talk a lot on the bus. I have noticed he try's to get my attention so we can talk by moving seats by me when I move. The other kids in our group aren't the smartest people in the world but everyone is my friend and they all are my neibors including the guy I like. Last year my friends kept yelling at him that I liked him at a football game. The next day I just ignored the whole thing but I know he thinks I like him but I don't know if he still does or feels the same way. Last Friday he invited me and one of my friends and my sister to a end of the year babeque with the rest of the people who ride my bus. I was the only one who came but my sister came later. When he brought out the s'mores and offered me one I said I didn't like marshmallows because they were so messy and then a few minutes later he was saying he didn't like marshmallows when I said I didn't like marshmallows he made me a s'more with out marshmallows and he kept asking if I was bored and said that it must be alward being the only girl at a party and when I said yah he kept asking if my sister was coming (she's a lot younger than me) we played a lot of games and stuff like that and one of the other guys there kept flirting with me like pulling me towards him and sitting close by me in a bench and I think the guy I liked noticed. Sorry this was so long! Does he like me?
