Try and understand why she would keep this hidden from you.
she doesnt want to do it or doesnt like what you are telling her...and doesnt want to tell you or you to know
tell her.
You don't.
if she has a wierd face expression
tell her that it upsets you whenever she doesnt reply tell her exactly how you feel. if she doesnt care then she isn't worth your time, but if she listens to you and replys then go with it
Go to the guy and tell him to tell his girlfriend that he has a crush on you and that he thinks they should get over each other.
Tell your brother about it. Tell her that his girlfriend makes you uncomfortable. if this doesnt work, try to make your brother look bad so shell break up with him.
He is probably just afraid that his exgirlfriend would get jellous and do some thing to his girlfriend, if she found out who his new girlfriend is.
because he does, he just isn't ready for a relationship.
He totally likes you, but he doesnt know what to do, like.. he doesnt know if you like him, he doesnt know if he should tell his girlfriend he likes someone else.. I can go on and on.. If you like him, tell him, he totally likes you.
Tell your ex. if he doesnt care he needs help...but also if its bad then you should tell someone
flirt with him/her and let him relize what you have that one girl doesnt have
