Is it really love? You tell me.?

I'm young, 15 to be exact and i've been dating a 16 year old boy for 6 months now. We've had arguments but we've always resolved them within the day, we play around, we joke, we laugh, but we also know how to settle down and have a serious conversation. I have had very strong feelings for him since the moment i laid eyes on him 2 years ago. I'm just curious, i want to know what I'm exactly feeling. Because im a girl whose afraid of letting people in. But he's the first person to have showed me that loving and losing is better than to never have loved at all. he makes me feel invincible, he makes me feel like i can do anything, anytime, anywhere. He makes a better person out of me. He's the reason I'm a straight A student, he's the reason I'm MVP in almost all my basketball games, he's the reason I am who i am, and the reason that who i am is exactly who i want to be. so is it love? Your opinioin.
