when shes with another guy
ask her out.
Speak out and let her get to know the real you, if she doesn't like it, forget her.
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
She's pretending let it go.
they will usually let you know if they like you back
no shes not cheating but she is a lucky girl and needs to let her bf know and let him get in the action
