-:he will ask for your handphone number....
sounds like a stalker

-:he will open another line which is same as yours (example, if you are using maxis, he will use maxis too ) >>> "ONLY HAPPEN WHEN THE BOY STILL HAVENT GOT HP"
This is what girls think but actually he is using another line just for you so that he wont get caught

-:sms you daily...
Again stalker..

-:shy when talking to you and act incredibly different in front of you...
Sounds like a psycho

-:try to call you everyday and talks about almost everything..(exp:what u doing ar ? , what time u sleep yesterday , what time u wake up , had meal already ar , and some other questions that tend to call u to out with him)...girls oso mus know how to do la..
Cue psycho theme song

What about this..
One day, go out with him, just the two of you. Gently hold his cheek, look into his eyes and see what he has to say. If he doesn't say anything and runs away then you have 2 option. A, if you like girly men, go after him and say you just wanted to know whether or not you two have chemistry or not and if he likes you he will spill his guts out for you and tell how he feels about you then, or B, just let him be and get a real man..
By the way its not hard for girls to look for guys, its the guys who has to do so much just to impress the girls.. From time to time its fun to have a girl who knows what she wants and when she wants it. Take control girl!
Good luck
