Well, a guy is definitely structured different from a girl.. A
guy gets attracted to someone at first sight, and falls in love
easily, sometimes says things he doesn't mean to get his
motive..
whereas when a girl likes someone, she falls in love over time, and
only say things when she means it, uses much of her emotions in
almost everything..
So if a guy keeps telling you that he loves you. Well, believe him
then but don't take it too seriously, afterall his 'love' and your
'love' has different definitions.. But if he says he's willing to
take care of you and shows no actions, then there's something to be
doubted.
