Boyfriend problem. I'm really confused with myself. Is it me or him?

I wanna make this simple. we've been dating for a month, im 14 and i just dont see us going anywhere. i get jealous when he's with other girls. i tell him i love him only to please him. im his first serious girl. he introduced me to both his parents and its only been a month.....he wants me to date him the entire year......he shows me off to his friends because im *european*? and he's super clingy. he always tries to snuggle with me and for some reason i dont like snuggling. i dont know why?? he likes kissing me alot and sure i like it to but dude. give me some time to breath. i dont wanna kiss 24/7. we're going to different schools and he's reallly good looking, on the football and basketball team. and alot of girls want him. and this gorgeous girl who looked like a younger version of megan fox was all over him and he hookedup with her. than left her for me....so like it made me feel special., but now im thinking i might wanna be with other people during highschool and he's taking this relationship so seriously and he wants to see me everyday but you know i got stuff to do.....like whats wrong with me ? ? am i just not a committed person? is it me or him? how do i tell him this?
