Whats the meaning to Nelly Furtados song say it right?

Whats the song about.
I dont understand her.
Whats the point of the song?
Sex?
Heart being broken?
What does she want you to say right?

"*In the day,in the night,say it all,say it right =
-Say "I Love You" if you mean it and youre really gonna show up to it (Day or Night...Not Just When Ur Sleeping Together), if not dont say it at all.
------------------------------...
2nd Part Of 1st Verse: (Following "Say It Right"
-You can either be a jerk or show me you love me (ALL THE TIME) you either love me or you feel nothing for me at all. Do what your heart tells you, because otherwise the "plan" is either to get some *** (From Nelly) or just plane ol BS.
------------------------------...
Chorus:
-If your gonna be a jerk, sleep with me, and not love me you can be **** to me. Everyone has the capacity to love which is what Nelly wants. If I had your love, then youd make me happy (set me free) and thats all i want (everything).
------------------------------...
2nd Verse:
I cant say that its my fault that im feeling confused (Lost). I cant say I want to date some kind of freakishly nice dude (light) but I cant have you thinking you can step all over me (dark) either. Nor can i say that i am oblivious to who you are and also goes back to "When Theres No Time For Jokin" bit which means, I only have one life and time is running out, i cant be wasting my time with your games.
------------------------------...
3rd Verse:
"Something I Made" and "Another Brick That Ive Laid" are pretty much saying "Ive worked too damn hard trying to live my life to the fullest, ive accomplished a lot, dont just screw it up. As for the whole "Body" bit, shes saying that you need to be worthy of it. Shes saying "A Place God Knows" because its the most precious thing shes got. (meaning her abstinence/ something like that... and you better be sure you love me or else youd be sinning (Which Is Why She Brings Up God) Im Hoping Its Not A Pun When Nelly Says "A Place God Knows, You Should Know Thiis Place Is Holy" and meaning God--->Holy---> Genitals... or else this song is complete bs along with the meaning ive been trying to explain... "

I got it from a user on songmeanings.net. Sorry, it might be a little long, but it was a better explanation than the other posts on the site.
