What would have a guy meant when he says that, "She is really nice,she is not like the ones I have known so far, she is different".Could it be a very casual statement or something like a crush?

Casual, is not big deal…

Did he say this to the girl?

I think I’d only say that if I had a crush on her.

I second the thought that he likes her. Otherwise that’s info I would keep to myself.

I think it’s a strange way of saying he’s interested. Though he seems confused that he’s interested!

definitely into her. kinda beating around the bush, but he’s into her.

well he didnot say this to the girl,instead he said to a friend who is a common friend to the girl as well!!

I still think the same….he likes her!!!!!!
