I would say the two that are Nate and Brooke. Well we all know Lucas Scott is not faithful he is damn cheater.

er no way luke obviously yer im totally with you... i was gonna pick nate at first but then went with brooke... its a hard pick between the too

Nathan and Haley are both VERY faithful to eachother, although they have made minor mistakes in their relationship they always remain true to eachother. I know people think Haley isn't faithful because of her kissing chris, but she was just confused... I think that besides a one mistake kiss she is VERY faithful.
I mean, Brooke slept with Chris when she was in love with Lucas and I consider her VERY VERY faithful.
Peyton, no... sorry. Love her, but she's made a lot of mistakes regarding relationships. She is very faithful at times though :] I think she just made a lot of slip ups in her life.
And Hell, we all know Lucas isn't faithful!

i wonder who's gonna pick lucas... :))

After Nathan & CArrie i`m on Brooke's side. But if that hadn`t happend Nathan ofcourse

to OTHbtowser: EVERYBODY is going to pick Lucas... xD

but who picks Peyton? she doesn't cheat on people she chates with people.. so WHO picks her ??

The only reason i chose Brooke over Nate was that he wasn't completley honest about the flirting with Carrie ..

and brooke too

technically peytons the only faithful one!

luke - godd so many i cant even keep up
haley - chris keller
brooke - slept with chris keller (kind of cheating, not fully cheating but in a way)
nathan - carrie (although i dont believe he was really, it was enough for haley to nearly divorce him)

peyton was involved in the affairs but she has never once cheated on the person she was dating! and that to me is what faithful is!

i know technically that counts brooke out of the unfaithful thing too! but brooke and nathan have soo many votes! i think peytons just as faithful as them two!

I agree with Laura plus don't forget the sex-tape! Nathan was faithfull with Haley but not with Peyton,,it's the same (I know he has changed a lot) but it counts!

Lucas haha It'd be HILARIOUS if someone picked him! I'd like to see the reason! He cheated on Brooke,on Lindsey..Peyton did something that NOBODY had done before! Lucas Scott did NOT cheat on her! OMG!

MOST faithful - i dunno! it's really hard to decide! Lucas.... well we all KNOW it's not lucas.

Nathan cheated on Peyton with Brooke AND kissed (kinda) Carrie.

Brooke slept with Chris Keller AND slept with Nathan (betraying Peyton i would say that counted as unfaithful)

Haley kissed (kinda) Chris Keller BUT then left with him i know that doesn't really count but for me it does and is actually worse than the kiss it's self.

Peyton nearly slept with Lucas while he was going out with Brooke - (for me the Brooke sleeping with Nathan counts which means so does this) as her being "unfaithful" to Brooke - if you know what i mean same way as Brooke was "unfaithful" to her. (Kiss with Lucas - you ALL know how i feel about that - i don't think it counts in the slightest and could literally kill someone for suggesting otherwise =P)

So to be honest i'd have to say Peyton is the most faithful, maybe, - WOW this is painful - drawing with Haley?!?!

agreed 1treehillfan !!
haley and nate are both faithful
SG1-090 haley didnt leave because of chris- she left for her music.

so lucas... well we all know that story.
brooke.. slept with chris keller + nate
peyton.. went after lucas TWICE while with her best friend, not faithful at all!
nathan... slept with brooke.
haley... one kiss with chris (which he actually went on to haley, but whatever..) + shes only ever slept with one person... her husband.

nobody picked lucas...big surprise there *sarcasm*
haha

def nate.
or peyton!

How is Nathan winning when he stood there and let Carrie kiss him? Don`t even get me started on Brooke.

ha no one picked lucas

they've all cheated on their boyfriend/girlfriend at some point except peyton...

1. Nathan cheated on Peyton with other girls & flirted with Carrie
2. Lucas cheated on Brooke and Lindsey with Peyton.
3. Brooke slept with Chris Keller and flirted with Lucas while she was with Felix.
4. Haley kissed Chris Keller when she was with Nathan [but it was more of a goodbye kiss IMO]
5. I don't think Peyton was ever unfaithful. When she was with Jake she kissed no one else, when she was with Luke she was only with Luke and the same goes for Julian.
