This is a touchy subject. I know it’s exciting to think about his motives, but it’s difficult for us to really know. I suggest you ask him to have a soda with you and to become friends.
Probably not. That seems like an awfully aggressively hassling way to do that. Seems he may be trying to annoy you, “hinting” he doesn’t like you. But, since we’re not there it’s hard to put into context and we’re not mind readers, it’s hard if not impossible to say for sure.
Guys don’t spend that long hinting that they don’t like the girl. They only spend that much time, and beyond, hinting they’re sexuall attracted to the girl.
