wow.. I think you should tell the dude you dont like how you feel. its better to be honest and take whatever happens then regret not doing anything. It seems like when you were trying to see if you liked him..You were sending mix signals??..I mean I understand what your going through.. It happend to me!!.. Lol.. Except i always ignored The fact that he liked me because we were good mates but thats all that i could see him as. And he totalli understood how i felt. He was all like..Its better to be friends with you thn nothing at all. As for the other guy.. Take a chance!.. If he doesnt turns out all that you wanted.. Theres many other guys in this world!!..
Hope this helps!!..
