what u need to do is first find something else to do and don;t spend much time on her why i am saying this is it because i don;t want u her to be your gf. no!!!!!!!!! from what i heard u call her and chat with her it seem like u do it everyday. stop doing that call a girl only two or three time a week. why am i saying this i will explain to u later. now let me give u an example pretend a girl really like u and she keep calling. and give u what ever u want, treating u like a king, even if u like that girl at first u will get tired of her after. u will think hey this girl really like me if i can get her to like me maybe i can get other girls. now do u know what i mean by stop calling her.
1.u are proving to her u dont; have a life and all u do all day is talk on a phone.
2.u sound like u desprately trying to get her no one like. and what a girl hate the most is a guy how bow down to her and treat her like a queen.
3. now u know that what u need to do is focus on something else this she will think hey this guy doesn;t pay much attention and then will make her chase after u.
there is a ton of stuff i wanted ot say but i am kinda lazy right now to write it all down but if u have any question just ask me.
