just tell him that both of you like him see who HE likes
You talk to your sister about it and tell her how you feel. Chances are, if she cares about you she will not date him. Don't ever let a guy come between the bond that you and your sister have. It will only bring jealousy and heartache; it's not worth it.
i think you need to talk to your crush about your friends crush who has a crush you on you and your sister knows about your crushes crush who wont tell you who they're like TOTALLY crushing on but they want to but promised your crush they wouldn't tell you who their crush was because their mom wont let her date and her sister is only a year older but she's allowed its SOOO not fair omg like wtf, and my sisters crush doesnt even like her so omg like LAWLZ!
Ask him if he likes u, and if he denies it tell him u have a crush on him and see if he says he likes u.
You can tell him that you like him and then he would probably say yes
see how they treat you.
ask them
He looks at you, touches you, or talks to you or about you.
depends on if you know he likes you or not
Just ask him, i asked my best guy friend if the guy i have a crush on likes me or who does he likes.....so just ask him and tell him not to tell anyone and if he does, oh well ur prolly not gunna see him when u go to college, and get married. SO JUST ASK HIM-----I DID-----
Tell him i don't think this is right, tell the truth.
If someone always wants to hang out at your house and never wants to go anywhere with you, they definitely have a crush on your sister. Also, if they ask a lot of questions about her, more so than about other things. If he stares at your sister or just ask him do you like my sister.
