How Should I Act?

UGH!!!!! Sorry, look. Honestly you should do whichever one sounds to you like it will work. Personally, I ABSOLUTELY HATE the idea that I have to pretend I don't like someone and they'll like me back. Mind games annoy me. And frankly things'll be easier if you're both truthful and honest with each other. If you act cold, he might think you just don't care any more, and heck he'd have reason to. Or he might do what you want. It's a chance a bet. But you know him best and you know yourself best. I'd keep talking to him, text him, speak to him. Closeness doesn't depend on how much someone texts you but how close you are. So feel free to join the "mind games" club. Personally I just hate it. And let the down voting commence

You're right too but it's always me who starts a conversation while texting and it doesn't last long.. And when he texts it's just about school things..That's why I get the feeling he doesn't want to talk to me or enjoy talking to me but we talk a lot in school..

Well some guys don't text that much either-so that's a possibility. I mean….when you're talking in person what's the impression you get then. Honestly it may not seem like it but that's the best judge you get of a person-not how much they text you

I tried not talking that much to him today just to see if he comes and tries to talk but guess what? We really didn't talk much today.. If I don't start a conversation we just become classmates.. That's makes me think the most.. I want to directly talk to him too but I'm shy and don't want him to misunderstand something.. Am I overthinking?

Don't play games with him. That's the fastest way to ruin everything! Be honest. Send him a txt and tell him how you feel. If he says he doesn't like you then move on to other things. At least you will know the truth. The truth shall set you free.

Both of you I'm really grateful for your advices. I decided to talk to him.. Thank you guys again! ^-^

Be honest with him. Tell him you'd like to talk more outside of school, if that's okay with him. Playing games with him isn't going to get you anywhere.
If you guys just don't click, you don't click. You can't force yourself to get along with someone exceptionally well and you can't force yourself to have things in common with them.
