The guy i like called me and my heart was beating really fast and loud?

Okay. So I have liked this guy since 6th grade i am now going into highschool. Now he finally notices me, and started talking to me. We have been talking for alittle over a month now. & he called me today and once i saw it was his number i heard my heart beating really fast and loud i couldnt even breathe. I dont know what went on but when i answered it we started talking and then when he asked me something i freaked out and got all tounge tied at one point. But i feel like an idiot and i feel that he wont like me because i got tounge tied and i just wasnt myself. Can you please help me and tell me what this means? and how i can feel more comfortable around him and when i talk to him? I dont think hes going to call me againD: but idk. how do i make him like me because i want him to be my boyfriend? but idk because hes a grade higher and we just started talking. He says he wants to hangout with me on Monday but im like freaking out because im scared but i really want to. I also forgot to mention he noticed me because i added him on facebook and then he started talking to me and he gave me his number. but since then hes called me cutie about 8 times so far. I know I had alot of questions but I hope you can try and answer them all(: thank you.
