FEELINGS FOR A GUY

So there is this guy that I like. We started talking a while back but then I got with his friend, but then me and him broke up and i thought this guy would now want to talk to me. Then one day i saw him on this website and i message thinking that he was never going to message me back he did. we started talking here and there then one night we say each other at a club. After the club he texted me and was doing that for a couple of days straight then he stopped and now when I text him he dont respond back. I see him on the website where I met him at and i want to message him but im scared that he dont want to talk to me no more. Well im going to message him and see what happens if he dont message me back then i guess he really didnt want to be with me. I Really want to be with this guy. to me he seems that he would be the perfect one for me :-(
