Why is he so attracted to you?

most likey it just depends on what type of guy your talking about if it is like some trouble maker dude that has a lot of diffrent girls all the time and does drugs and hangs around the wrong crowd of people most likey he is just using you for sex he is being nice to you to get in your pants but not all guys are like that he mite be just being nice to you because he actually really really does like you alot and is hopeing you thank him for being nice to you and wants a long term relationship with you
