if you really like this guy, then get to know him..you should like guys for their personality's as well as looks...so once you get to know him then you can decide if you really like him. Who know's you might actually really hate him.
Dump your boyfriend first, if he treats you like crap then he's really not worth it. Then you can start flirting with this new guy or anyone you like. Try not to go back to the original boyfriend as tempting as it seems.
I'm not sure if this will help but does your boyfriend like your cousin? If you have faith in your boyfriend then even if your cousin really DOES like him, you know that your boyfriend won't cheat on you. If he really does cheat on you then all i can say is - you deserve better than that. As to how to tell ... I guess you can talk to your cousin about it? or you try to talk about your boyfriend to your cousin and notice her reactions and expressions.
Sweetie, your 12, you have much time to worry about a boyfriend! You have a whole life ahead of you! Wow i sound like my mom! haha but If you really want a guy to like you be kinda flirty, make him notice you! Stuff like that! Anyways good luck girl:) -Kayleigh
he's already u r boyfriend, so he knows you really like him.
Well yeah, if he is your boyfriend he will really like you O_o
Dump your boyfriend
It depends if the boyfriend doesnt treat you right then my choice would be the boy you really like.
just act like yourself and then he'll notice
You show you really really like him.
Just be yourself. If he really digs you, he will like you for who you really are.
If he is already your boyfriend, he must like you.
If she is dating him, it doesn't really sound like he is your boyfriend.
