There were a lot of really good (and so many bad) relationships on the CW classic teen drama, One Tree Hill. Here is a list of twelve of the most remembered OTH realtionships, ranked from worst to best:

12. Dan and Deb. Maybe an obvious one. They got married young because she was pregnant with his child. She watched for years as Dan bullied and pressured their son, Nathan, with his basket all career. Their relationship became strained, resulting in her taking pills and becoming an alcoholic. When they divorced, the viewers screamed HALLELUJAH.

11. Nathan and Peyton. Ah, yes. The "power couple" of Tree Hill High. Too bad Nathan couldn't care less about her feelings and lifestyle. He had no respect for her and often chose his social/basketball life over her. Their constant arugments/break ups always led to unhealthy make up sex. She was a lonely mess throughout the relationship, but was finally strong enough to end their relationship.

10. Lindsey and Lucas. They probably would've been an OK couple if Peyton hadn't come back into the picture. But then again, Lindsey pretty much rubbed her engagement to Lucas in Peyton's face. She even befriended Peyton's best friends! Thankfully, Lindsey finally caught on to the love Peyton and Lucas still had for each other and left Lucas on their wedding day (ouch).

9. Dan and Rachel. Two of the most evil characters on the show got married and created more evil. They helped each other out during the dark times in their lives, and even created a self-help TV show together. Although the marriage ended, they were a decent couple in the fact that they helped each other out with redeeming themselves.

8. Mouth and Millie. They started out nice, especially because Mouth hadn't had a real girlfriend the entire series. Soon Millie became a model and lost all self-control. She started doing cocaine and got arrested for a DUI, and Mouth being Mouth broke up with her for her behavior. The two got back together and became the cute couple again.

7. Lucas and Brooke. Although Brooke started out as the slutty high school cheerleader, her relationship with Lucas was the first step towards the woman she developed into throughout the series. He was the first boy to listen to her stories about her neglectful parents and her insecurities. Their on-and-off again relationship had a lot to do with Peyton, her best friend and his future wife. While they were together, however, they seemed perfect for each other.

6. Peyton and Jake. Oh, Jake, we miss you. After the whole Lucas thing, Peyton found her way to Jake: the single father basketball player whom we all fell in love with. She babysat for his daughter, Jenny, and they soon developed feelings for each other. However, Jake's crazy-ex and Jenny's mother, Nicki, put several strains on their relationship. He was sent to jail for custody reasons and Jenny was kidnapped by Nicki. Let's just say, despite all of the craziness, Jake and Peyton were great for each other and she would have made an excellent step-mom to Jenny.

5. Quinn and Clay. Although seasons 7-9 were SUPER UNNECESSARY, a great couple came out of them. Clay and Quinn both appeared in the first episode of season 7 and we knew they were meant for each other. He started out as a player and she was trying to get away from her marriage. When they began dating, the viewers felt the same spark they had when Nathan and Haley got together. Let's not forget to mention that they fought off Clay's crazy stalker, too. Power couple.

4. Brooke and Julian. Brooke had been hurt by her past relationships, particularly with Lucas. When Julian came into the picture, she wasn't sure whether or not she should fall for him, considering he was an ex of her best friend, Peyton. Brooke finally let her guard down and accepted their love. Their relationship had many rough patches, including her inability to have children and Alex Durpre's feelings for Julian. The two eventually got married and, by a miracle, gives birth to twin boys.

3. Lucas and Peyton. The relationship we knew would happen since the first episode. Troubled girl meets boy who is ready to help her with all of her problems. Even though it took SIX seasons for them to FINALLY get married, we always knew they were endgame. Their obstacles were overlooked and they finally gave into the fact that they were meant for each other, even if it meant splitting up Lindsey and Lucas' engagement.

2. Karen and Keith. Keith was the ultimate dream man. He helped Karen raise Lucas in his father's absence and genuinely loved Karen since they were teenagers. he waited years and YEARS to reveal his feelings, and when he did the world was perfect. they got engaged and she was pregnant with his child. But, they never got their happy ever after. Keith's beautiful life was taken much too soon, but their daughter grew into a wonderful girl and his legacy will always be remembered by Karen, Lucas, and the viewers.

1. Nathan and Haley. We all knew this was coming. One of the only couples in TV history to last the duration of the series. Nathan's bad boy behavior was broken by Haley's huge heart and the two became a match made in heaven. They married in their junior year of high school and she gave birth to their son after graduation. Even though they were young, their love was strong and mature enough to face any obstacles. Their love has become a phenomenon and the fans will remember them "always and forever."
