personally, i feel that everyday is too much.... but it really varies.. i usually say it at fairly random times... but i try my best to find at least 1 random time a week to at least tell her....

but i usually prefer the "i will show her i love her" route instead... be creative, buy her some flowers when she isn't expecting it.. (for all you kids in school, like me, buy her some flowers and TAKE THEM TO HER WHEN SHE IS IN CLASS.. this is generally best when you are in high school though.. small classes, and interrupting a class won't get you killed... bonus points if you don't even go to her school)

or you could make her a nice meal (or take her out to one if you can't cook)...

or you could simply just go meet her when she isn't expecting you... ie: this one time, my ex was in a performance, and i rushed my ass all the way there just in time to catch her before she went on... granted she cryed a little before she went on

oh, and for the flower thing, if she gets embarassed easily, scratch that whole school thing.. cuz she'll kill you

but the best way to make a gurl feel loved is not by telling her, but by showing her (or at least in my limited experience, this is the case)

*Edit after seeing Sugar&Spice's post: my point exactly... saying it constantly makes it lose it's value
