Any advice on a boyfriend/crush problem?

Here's my problem: I have a boyfriend and he's 12, one year older than me and in 6th grade like me. I REALLY REALLY like him. Not just because he's cool looking. but because he has a great personality. My boyfriend has an older brother and he's going to be 14 this summer and he's in 8th grade and I have a crush on him. I like my boyfriend more than him, but at school when he passes by and after school when I see him, I just can't resist but stare at him and try to get his attention. I won't cheat on my boyfriend because I am not sure if his older brother likes me. But is it wrong to like someone else if you already had a boyfriend? Any advice on how to overcome this crush? I don't want my boyfriend to find out about this.Any advice on a boyfriend/crush problem?
holy crap ur 11. Chill out...a crush when ur that young will only last for a month at the longest. Hang out with this guy as a friend, but thats it (unless u both like each other)Any advice on a boyfriend/crush problem?
i agree with erica. when i was 13 (not much more mature than you) i had a crush on SIX different guys. i think you'll be fine.
omg! You are 11! You're too young to go with a 14 year old. Though he isn't mature, he's more so than you are. Really, you're too young for a boyfriend at all (I'm 17- I've been there). Chill out and wait for those problems when you're older, girl!
