hmm wow ive never had any problems with getting girls that i like but my advice has helped friends out so i guess talk to her and just get to know her better and once you start to become a little closer and build up trust.. tell her you like her.. just dont make it to soon but usually when you feel like yous are becoming decently good friends thats about the right time. this is usually what happens when i talk to a girl i like
ME: hey whats up?
HER: nothing much just blah blah blah
ME: Oh thats pretty cool, do you want some help? or aw thats pretty stuff i can help you out if you want? just to make it easier for you
basically the trick is to just keep the conversation going... no conversation killers like "oh thats pretty cool" its your job to lead the way even talk to her about music she likes, hobbies she lieks doing and just elaborate onto the subject... when it seems like tis going to die switch to another subject
