Lost, like many shows and movies, features a very prevalent theme of love and difficulty in relationships. Nearly every character in the show is affected (including the Others), at least to some level, by this theme.
Details: Jack married Sarah, a girl whom he had impossibly saved by repairing her spine. Sarah had been involved in a horrific collision with an SUV (driven by Adam Rutherford, Shannon's father), but, despite all the odds, Jack saved her, and, in the end, they married on the beach. The night before the wedding, Jack got cold feet, and had great difficulty writing his vows. In the end, it was his father who managed to steer him through it. However, over time, Jack's relationship with Sarah began to deteriorate; culminating when Jack kissed another woman whose father was a patient of Jack's. It mattered little in the end, though, because Sarah planned to leave Jack anyway. The two got divorced, and Sarah found someone else. Jack began to obsess over the identity of the new man, falsely believing for a time that it was his father.
Details: When she played I never with Sawyer, it was revealed that Kate had been married in the past, but, at the time she did not reveal to whom. Later, we find out that she was married to Kevin, a police officer from Miami. ("I Do") They shared marital bliss for a while, and it appeared that Kate's feelings for him were genuine; she rang the marshal and pleaded for him to stop chasing her so she could live happily. The marshal promised to do so, but only if she stayed put and did not go anywhere. However, she could not reconcile herself to the ordinary lifestyle that living with Kevin would entail. Therefore, she resorted to drugging Kevin, before resuming life on the run.
Kate has also had a minor relationship with Tom Brennan; the two were childhood sweethearts, and buried a time capsule together when they were younger. They kissed, and sparks appeared to be there, until Tom was killed in a road accident as Kate attempted to escape from police once more.
Details: James "Sawyer" Ford has a reputation for being a ladies man, and that is not without substance. Sawyer has seemingly been unable to hold down any serious relationships, as his tough exterior stops him from getting too close to people. Indeed, he says on the Island that he has never properly been in love. Generally, he sleeps with people (such as Mary Jo and Jessica) as part of his cons, and then leaves them, moving on to his next victim. However, there was one girl who appeared to tug at his heartstrings more than any other: Cassidy.
Cassidy started off as one of his con victims, but it appeared that he began to harbour feelings for her, so much so that he attempted to call off the con, only to be forced to continue. It was later revealed that Sawyer possibly has a daughter by Cassidy, named Clementine. It is unknown as yet whether Sawyer has had any contact with his daughter.
Details: Charlie targets Lucy Heatherton, a rich British woman from Knightsbridge, in order to steal money for heroin. Lucy's father owns a rich corporation, which enables him and his daughter to live in comfort in a big house, with lots of precious artifacts and interesting ornaments. Lucy's father gets him a job at his company, selling photocopiers. However, before his first day, he had been unable to get a fix, meaning that he was suffering heroin withdrawal. This resulted in his first day being an absolute disaster, and it meant that Lucy found out of his addiction, dumping him as a result. He also gives back what he stole, attempting to make amends, but to no avail.
Charlie also slept with another woman named Lily the night before the crash. However, this was not the makings of a serious relationship; the girl was only interested in his heroin stash, and fought him for it.
Locke

Relationship:Helen(girlfriend whom he proposed to)
Details: John Locke's first real relationship (to our knowledge) is with a woman called Helen.

Locke begins staying at her house overnight, but, he leaves in the middle of the night, for reasons unknown. Eventually, she catches him while doing this. He feeds her an excuse, about not being able to sleep in beds other than his own. However, his real reasons are revealed when Helen follows him; he has been spending the early hours in his car, outside his father's house. Helen is deeply upset by these turn of events, and feels like Locke would prefer his father to love him more than her. Since then, although Helen takes him back, Anthony Cooper has proven a source of tension between them. Later, Locke decides that Helen is the woman for him, and proposes. However, she rejects him, citing his relationship with his father and his constant lies as proof that she cannot trusts him. Locke is left heartbroken, and, in the end, resorts to spending a large amount of money on who appears to be a phone sex operator whom he has become infatuated with. However, he scares her away too, inviting her on a walkabout tour of Australia. She refuses, and he is on his own once more.
