Does my crush actually like me more than his current girlfriend?

I am in 8th grade and I really like this 7th grade boy. He currently has a girlfriend (they hang out together a lot (not alone), they have kissed on the cheek once, etc.) but I am feeling like there is a possibility that he may like me more. When they first started hanging out (before it really became a relationship) he tried talking to me at youth group one day but I gave him a short answer cause I was shy and showed many other signs of liking me. Then they started hanging out a lot but he still seemed to really like me. And one time at youth group he saw me come in and kept glancing at me and then the other girl came in and he saw but didn't even go over and say hi to her. Then when one of his guy friends came in, he went over to him and then he said something to him as if he was complaining or disappointed about something and they both looked at me. And once I had to stay in the cafeteria during recess and I was looking out the window at him and I saw that he was looking for me and then he saw me looking out the window and he and some guys played ball near there, when he could have been hanging with her. Now they are pretty close and he is still turning around and looking at me even when he is with or talking to her and showing many signs. Do you think there's a possibility that he likes me more than his current gf? Please help, I'm really hurt that he has one!!!
