Well when a girls says that she likes you it mean that she is feeling ready to tell you! You should do the same when your ready tell her
Well you should have somebody you know that is a girl say something like "oh, that guy is checking you out" exedera
tell her
You should let her know how you feel im 15 and the most things in our relationship is honesty.
Tell them!
Unfortunately you have to respect her, let her be and move on.
You should leave her alone for awile then talk to her in a day or to and keep talking to her to let her get to know you. From, Alison
If she knows you well, then you should tell her that you love her. There is no harm in telling her. It isn't like she is going to freak out and never talk to you.
Say that you like something about her like that she is pretty. That's enough to let a girl know you like her
Speak out and let her get to know the real you, if she doesn't like it, forget her.
If you are close to this guy then you should just let him know how you feel and if he continues to go out with this other girl you should just move on. Hope i Helped!
Let her know you like her, Imma girl, If she doesn't respond positively she isn't the right one. A girl will let you know she likes you, depending on the girl she is, or will talk with you a lot or won't talk a all :) Good Luck
they will usually let you know if they like you back
