i have a feeling that they aren't together anymore. i think he wasn't man enough for her. he seems like a bit two-faced and absorbed in himself. but we shall see!
Amy said in Brazil she was missing him, but I think that "dating" is nothing more than an "accord" (don't know if it's correct in english). Amy and Blake loved each other in a way that everyone could feel that, but I don't see love between Amy and Reg.
