At the start, friends told me he like me. And yes I can feel it. We sms a lot to each other, but lately, when I went out with my friend today, she told me he has a girl friend and this shocks me. He lately didn't really reply my message either. Im sad, what should I do?

Well, very simple. Get over it.
I can't believe that you would actually believe everything your friends told you. It's just what they said, he never confirmed it right? I was in the same situation once. And at first, I, too, was dumb enough to believe what those people said, but eventually I did my small investigation and it turned out it was all just a big joke.
Maybe he Did like you, but after texting for awhile he found out you are not suitable for him, that's why he stops, as simple as that.
You also felt that he liked you? Dude, that's what people call delusional thoughts. Because friends said he liked you, you started to think that he actually liked you, and everything he did suddenly had a hidden meaning that said "Hey I like you". That's the most normal reaction for a girl so don't worry. Just be cool.

Hi aleeravilu, thanks for your answer. But at the same time, that was my most trusted friend, and she made a mistake, that was that guy didn't had a girlfriend.. I can easily know he likes me , because last time we have some feelings and we declare tgt.

Anyway, thanks for your answer though, I have forgotten about him already. Hehe!

Well you can't listen to people all the time, even if they're your best friends.
Anyway, nice to know you got over it. Cheers :D
