I wasn't implying they had never been there for Peyton, I just thought it was highly strange that Nathan and Haley never once went to see her or even ask Lucas how she was doing with nearly being raped/killed by Psycho Derek. I mean, I can get why Brooke didn't, but for Naley to just ignore her, in my opinion, was way OOC.
Although I agree that it has to do with poor writing and ignoring established friendships to prop up a couple or storyline.
Also, I've noticed that Peyton/Haley's friendship was one of the most inconsistently written through the first six seasons. They don't interact, only to have each other yell at one another, make up, and then don't interact again for episodes on end, while Brooke/Haley is proppped up to be the second coming of Breyton.
