I wanna die :( :( :( :( I feel so used and miserable right now! why did this happen to me?! :(?

this dude from french cl who I'm not sure likes me, on bmm and on facebook whenever we chat and whenever I say something funny which is most of the time cuz I can be hilarious sometimes haha he's like lol *flips out* and he calls me wacko and he nicknamed me scooby and when i told him about this guy who liked me he was like 'scooby he soo wanted to get with you' and he also called me cute and was like u know i would so date you so how do u know if a guy really likes u or if he just wants to get into your pants? also he said these same things to my best friend, we were chatting today and we came to know! wow! I feel so used right now! why did he do this to us?! i feel so bad right now! did he really like me and if he did why did he do this?! :(
