卢平非常爱唐克斯，卢平喜欢过莉莉，但仅仅是学生时代的好感与一时迷恋。
1. 卢平对莉莉的好感
阿方索导演的《囚徒》电影里有一段改编恨深入人心，卢平和哈利在桥上聊天，对就是《死圣下》电影里纳威和西莫炸掉的桥。当时这个改动被很多哈迷诟病，怎么搞得卢平像是喜欢哈利他妈一样，结果罗琳阿姨说，卢平真的喜欢过莉莉。
罗琳访谈里的原话是：
Lupin was very fond of Lily. We’ll put it like that, but I wouldn’t want anyone to run around thinking that he competed with James for her. She was a popular girl, and that is relevant. But I think you’ve seen that already. She was a bit of a catch.
渣翻译:
卢平曾经非常喜欢莉莉。我这么说吧，我不想让你们产生误解。卢平从来没有为了莉莉和詹姆竞争，她是个受欢迎的女孩，卢平喜欢她也和这个有关系。我觉得你们已经看出来了，她当时非常抢手。
我觉得卢平对莉莉远远谈不上爱，罗琳也没有用love，仅仅是青春时期的好感和对美好的向往。莉莉当时是万人迷，就像后来的金7妮，不仅漂亮，还性格好、勇敢、有正义感、有天分、双商具高……是个在人群里非常耀眼的女巫。卢平却一直很自卑，因为狼人身份；因为从来没想到像小天狼星和詹姆这么耀眼的人再知道真相之后还会和他是朋友……他被莉莉吸引也是很正常的事，但这种喜爱之情对卢平来说绝对没有和詹姆的友谊重要。
2.卢平对唐克斯的爱
卢平真正爱的人只有唐克斯。
pottermore的原文：
Marriage
As Lord Voldemort once again gained ascendancy, the old resistance regrouped and Remus found himself once more part of the Order of the Phoenix.
This time, the group included an Auror who had been too young to belong to the Order during its first incarnation. Clever, brave and funny, pink-haired Nymphadora Tonks was a protégée of Alastor ‘Mad-Eye’ Moody, the toughest and most grizzled Auror of them all.
Remus, so often melancholy and lonely, was first amused, then impressed, then seriously smitten by the young witch. He had never fallen in love before. If it had happened in peacetime, Remus would have simply taken himself off to a new place and a new job, so that he did not have to endure the pain of watching Tonks fall in love with a handsome, young wizard in the Auror office, which was what he expected to happen. However, this was war; they were both needed in the Order of the Phoenix, and nobody knew what the next day would bring. Remus felt justified in remaining exactly where he was, keeping his feelings to himself but secretly rejoicing every time somebody paired him with Tonks on some overnight mission.
It had never occurred to Remus that Tonks could return his feelings because he had become so used to considering himself unclean and unworthy. One night when they lay in hiding outside a known Death Eater’s house, after a year of increasingly warm friendship, Tonks made an idle remark about one of their fellow Order members (‘He’s still handsome, isn’t he, even after Azkaban?’). Before he could stop himself, Remus had replied bitterly that he supposed she had fallen for his old friend (‘He always got the women.’). At this, Tonks became suddenly angry. ‘You’d know perfectly well who I’ve fallen for, if you weren’t too busy feeling sorry for yourself to notice.’
Remus’s immediate response was a happiness he had never experienced in his life, but this was extinguished almost at once by a sense of crushing duty. He had always known that he could not marry and run the risk of passing on his painful, shameful condition. He therefore pretended not to understand Tonks, which did not fool her at all. Wiser than Remus, she was sure that he loved her, but that he was refusing to admit it out of mistaken nobility. However, he avoided any further excursions with her, barely talked to her, and started volunteering for the most dangerous missions. Tonks became desperately unhappy, convinced not only that the man she loved would never willingly spend time with her again, but also that he might walk to his death rather than admit his feelings.
Remus and Tonks both fought Lord Voldemort and his Death Eaters in the Department of Mysteries, a battle that resulted in the public exposure of Voldemort’s return. The loss of the last of his school friends during this battle did nothing to soften Remus’s increasingly self-destructive attitude. Tonks could only watch in despair as he volunteered to spy for the Order, leaving to live among fellow werewolves to try to persuade them to Dumbledore’s side. In doing this, he was exposing himself to the possible reprisals of the werewolf who had changed his life forever, Fenrir Greyback.
Remus came face-to-face with both Greyback and Tonks at Hogwarts barely a year later, when the Order clashed with Death Eaters within the castle. During this battle, Remus lost yet another person he had loved: Albus Dumbledore. Dumbledore had been adored by every member of the Order of the Phoenix, but to Remus, he had represented the sort of kindness, tolerance and understanding that he had received from nobody in the world outside his parents and his three best friends, and had been the only man ever to offer him a position within normal wizarding society.
In the aftermath of the bloody fight, inspired by Fleur Delacour’s protestation of enduring love for Bill Weasley, who had been savaged by Greyback, Tonks made a brave, public declaration of her feelings for Remus, who was forced to admit the strength of his love for her. In spite of continuing misgivings that he was acting selfishly, Remus married Tonks quietly in the north of Scotland, with witnesses taken from the local wizarding tavern. He continued to fear that the stigma attached to him would infect his wife and wished for no fanfare around their union; he swung constantly between elation that he was married to the woman of his dreams and terror of what he might have brought upon them both.

婚姻
伏地魔再一次崛起时，原来的抵抗力量也重新聚集起来，莱姆斯又成了凤凰社的一员。
这一回，凤凰社吸纳了一名上次成立时还太过年轻的傲罗——尼法朵拉·唐克斯，她聪明、勇敢又风趣，有一头粉红色的头发，是「疯眼汉」阿拉斯托·穆迪的门生。穆迪则是傲罗里最强悍，也最年长，最厉害的一个。
常常忧郁孤独的莱姆斯一开始觉得这个年轻的女巫很有趣，后来对她刮目相看，再后来深深地爱上了她。他以前从来没坠入过爱河。要是这发生在和平时期，莱姆斯会直接离开去一个新的地方，找一份新的工作，这样他就不必忍受痛苦，眼看着唐克斯如他预料的那样爱上傲罗办公室里某个英俊年轻的巫师。可那是在战争时期，凤凰社需要他们俩，而且没人知道明天会发生什么。莱姆斯觉得自己有理由留在原地哪儿也不去，他把自己的感情埋在心底，可每次有人派他和唐克斯一起在夜里执行任务他都暗自高兴。
莱姆斯从没想到唐克斯会回应他的感情，因为他总觉得自己不干净，也配不上她。一年的磨合让他们的友谊渐渐升温，有天晚上他们一起躺着躲在一个知名的食死徒家屋外，唐克斯随口议论了两句凤凰社的一名同事（「就算在阿兹卡班呆过，他还是很帅，不是吗？」）莱姆斯没来得及住口就幽幽地说，他料想唐克斯喜欢上了他的老朋友（「他总是很有女人缘。」）听了这话，唐克斯突然非常生气，说道：「要是你没那么忙只顾自怨自艾而注意不到，你就应该很清楚我喜欢的到底是谁。」
莱姆斯第一反应是感到前所未有的幸福，可幸福感几乎立马就被沉重的责任感浇灭了。他向来知道自己不能结婚，也不能冒险把自己痛苦而可耻的病传给下一代。所以他假装没懂唐克斯的意思，可那根本就骗不了她。唐克斯比莱姆斯更聪明，她可以肯定莱姆斯喜欢她，可是出于某些高尚但错误的原因却拒绝承认。尽管如此，他开始逃避，不再和她一起出行，也几乎不和她说话，并自告奋勇去执行最危险的任务。唐克斯难过极了，她确信她爱的人再也不会乐意和她在一起，而且他宁死也不愿承认自己的感情。
莱姆斯和唐克斯两人都在神秘事务司里参与了抗击伏地魔和食死徒，这场战斗令伏地魔的回归大白于天下。战斗中莱姆斯失去了他最后一个同窗好友，可那一点也没缓和他越来越严重的自毁倾向。唐克斯只能绝望地看着他自愿为凤凰社当眼线，去和狼人住在一起，试图说服他们加入邓布利多的阵营。这样做他就将自己置于被狼人报复的危险之中，那个狼人正是改变他人生的芬里尔·格雷伯克。
仅仅一年后，凤凰社在城堡里和食死徒交战时，莱姆斯在霍格沃茨面对面遭遇了格雷伯克和唐克斯。这次战斗中，莱姆斯又失去了一位他所爱的人：阿不思·邓布利多。邓布利多受到每个凤凰社成员的爱戴，但对于莱姆斯而言，他代表了善良、宽容和理解。除了邓布利多，莱姆斯只在他父母和三个最好的朋友那里感受过这种关爱，而且邓布利多也是唯一一个在正常巫师社会里提供给他工作岗位的人。
那场血腥的战斗过后，比尔·韦斯莱被格雷伯克严重咬伤，但芙蓉·德拉库尔仍表明了她不渝的爱，唐克斯受到激励，也勇敢地公开表白了她对莱姆斯的感情，莱姆斯被迫承认了自己对她的爱有多深。尽管他仍有重重疑虑，觉得自己十分自私，莱姆斯还是悄悄地在苏格兰北部和唐克斯结婚了，由当地一家巫师小酒店里的人们做见证。他依旧害怕自己的烙印会影响到他的妻子，不希望他们的结合让太多人知道。他常常在欣喜和恐惧间摇摆，喜的是他娶了自己的梦中人，惧的是他可能给他们两人带来的后果。
是反伏地魔运动把卢平和唐克斯聚在一起的，一开始卢平觉得唐克斯很有趣，然后佩服她，最后深深地爱上了他。卢平从小到大都一直在自卑、犹豫。我无法想象伏地魔倒台后的那12年他是怎么过的，当时所有人都以为小天狼星害死了詹姆、莉莉和彼得，等于一个最好的朋友杀死了另外两个他最好的朋友，而友情一直都是卢平的所有。他回到霍格沃茨，终于了解了真相，事情好转了那么一点点，短短两年后他仅剩的好朋友也离开了，卢平一直都被充满欢乐的人吸引，詹姆和小天狼星就是制造欢乐的人，唐克斯也是，《凤凰社》里她第一次登场，笨手笨脚，每十分钟就要绊倒什么东西，变形逗人开心，总是很活泼轻快，又顶着一头泡泡糖色头发。
有着共同的追求和奋斗目标、都在黑魔法防御术上非常出色，一个被欢乐吸引，一个全身每个毛孔都散发着快乐的气息，但爱情往往讲不清理由。
我觉得最能体现出卢平真的非常爱唐克斯、只爱过唐克斯的是，卢平因为唐克斯才真正的得到了救赎。
卢平其实并不是一个勇敢的人，甚至有点懦弱，他为了凤凰社出生入死，从来不拒绝危险的任务，去狼人内部当奸细，甚至有点自毁倾向，因为他不怕这些，对他来说算不了什么。卢平害怕不被接纳、害怕被排斥、害怕面对自己的感情，就转身投入最危险的工作。小天狼心死后他去卧底，唐克斯怀孕了他要跟着哈利三人，因为他不敢面对。
哈利给自己曾经的老师好好上了一课，卢平也意识到了自己真正最重要的责任在哪，终于能够克服一直以来的心病，出于对唐克斯的爱。
