Help? Anyone? Please?

Ok, I have a friend named Curtis, and he's very attractive, I think I might like him, well, when we're outside, it feels like he`s ignoring me, he`s always with his friends, but when we talk online, he always flirts with me,he tells me i'm hot,pretty, and beautiful. Also he`s very caring and tells me he loves me, I think from my point of view , he`s two-faced, should i continue to like him ? Why or Why not?
