I think you have missed the point. Even in the beginning of AOTC, Padme makes comments that SHE doesn't like the way Anakin looks at her! We don't know if Anakin turns violent against her in Ep. 3, as for what we have seen in AOTC, I wouldn't find it out of character in Anakin, since he is becoming Vader... I mean this is the same guy that cut his own son's hand off! It is Anakin's comments to Obi-Wan that add to the "stalker behavior" not as much as his interaction with her. He still doesn't come off as a "love-sick" teen IMO. If I talked like that to a girl,and acted like Anakin does, I don't expect her to marry me!
