He sends you sms? Yeah...it's not a big deal, he does it to his other friends
He shows that he care? O really? He just try to be a good person
He chats with you everyday? Well, he need to talk with some one, he chats with the other also while he was chatting with you.
He knows and remembers your birthday? Hellooooo, it's easy to get that information nowadays, your Facebook shows it.
And the most important thing is...... HE's JUST NOT THAT INTO YOU....
If he is, he will say it.
So, continue your life and open your eyes for this world offers so many thing for you.
~ and so the decision has been made, let it go!~
