She laghs at you, she smiles, and then you ask here out!
Well if the girl seems to spend a lot of time looking at you, or blushes when you talk to her, always seems to be close to you, could all be signs that she is interested in you.
Flirting with her all the time, spending a lot of time with her, and giving her flirty compliments.
When a guy is interested in you he flirts alot emails you alot and mabey wants to talk to you alot more than usual...and if he asks who you are interested in he's wanting to know if you are interested in him also he smiles at you in a different way than usual or he is a show-off in front of you those are the most obvious signs that I know of.
If the girl in question likes you then you won't need to convince her to let you be her boyfriend, you must wait for the signs to see if you think she is interested, let the girl make the move, don't be pushy, be patient.
Side glances Smiles at you if you talk to her Sometimes gets a bit nervous Asks for stuff such as paper Asks/offers help Acts different around you, but really outgoing with her friends These are the signs i get
it depends what girl
She keeps asking you out. :P
If a girl is not interested then she is not interested, don't try to persuade her or pressure her to it. find someone else who is interested.
It depends on his relationship with his current girlfriend. Are they having problems? If yes, then maybe he is interested. If not, then he might be just wanted to be your friend and actually cares about you as a friend. Or, he is trying to cheat on his girlfriend.
You should show signs that you like him (flirt), and then if he shows you signs that he likes you back, then that means he must be interested.
you could talk to her about something that she is interested in or You find one who is.
