<P> As their marriage continues, Haley and Nathan seem to encounter more and more hardships as a young couple, realizing that their marriage might hinder their dreams; Nathan's dream being basketball and the NBA, and Haley's dream being music . With the arrival of Haley's older sister, Taylor, the couple has their first big fight, as it is revealed that Nathan lost his virginity to Taylor his freshman year . Also with the arrival of Chris Keller, a conceited albeit talented musician, the problems in the marriage are escalated, due to Nathan's jealousy and distrust of Chris . As Haley and Chris begin to spend more and more time together, recording a duet of Ryan Adams' "When the Stars Go Blue," they realize that they have a strong musical connection . This, of course, angers Nathan even more, especially when he realizes that Chris' feelings for his wife are not exactly platonic . </P> <P> When Haley is offered a once - in - a-lifetime opportunity to go on tour with Chris Keller, The Wreckers (Michelle Branch and Jessica Harp) and Gavin DeGraw and after confessing that she kissed Chris, Nathan is outraged and gives Haley an ultimatum; if she goes on the tour, their marriage is over . Haley is hurt and ultimately decides that she needs to follow her dreams . She reluctantly accepts Chris' offer, unlike Nathan who had refused his dream of attending High Flyers (earlier in the season), an elite basketball camp just to be with his wife . Haley's leaving sends Nathan on a downward spiral, but Haley fulfills her dreams by building a music career and by performing her songs in front of huge crowds . </P> <P> Though it is made clear numerous times that she regrets leaving Nathan, when he visits her on tour, he is unable to convince her to return to Tree Hill . Near the end of Season 2, she receives a petition for annulment for the marriage to Nathan Scott, leaving Haley heartbroken and filled with regret . Shortly after, Haley is visited by Lucas and Brooke at one of her shows in New York . Lucas tells Haley that although he is so proud of everything she has accomplished, her absence is simply "killing" Nathan . In the end, it is Lucas and Brooke's visit that convinces her to return to Tree Hill and to Nathan . In one of the final scenes of the (second season) finale, she shows up at the Scott residence doorstep . Her intentions aren't made clear until the third - season premiere . </P> <P> At the outset of Season 3, Haley returned to Tree Hill to find that many things have changed during her absence . Although she professes her undying love for Nathan and begs for his forgiveness, their marriage continues to fall apart . Nathan's anger and inability to trust Haley leads him to strongly consider a divorce . (However, the state requires a year - long period of separation, in which circumstances improved .) Haley also finds that her close friend, Peyton, has flat - out refused to speak to her, as Peyton is also angry and hurt by Haley's sudden departure and how it effected her friend Nathan as well . Haley is faced with a dilemma because, since Nathan moved back into his parents' house and her own parents are traveling the country in an RV, she has nowhere to live . In the end, she moves into her former apartment with Brooke Davis (Sophia Bush) and becomes a cheerleader . </P>
