"I hate women. All they do is cry all the time."
Theodore plays a video game in which a small alien creature with a filthy mouth interacts with him sometimes. On the eve of his blind date, Theodore tells the character about it and the character replies with this. This line is an instance of explicit misogyny that Theodore laughs off. He dismisses the video game character; he likes women and he is motivated to go on a date.
"Sometimes I think I have felt everything I'm ever gonna feel. And from here on out, I'm not gonna feel anything new. Just lesser versions of what I've already felt."
Theodore's emotional crisis links to themes which pervade the film. Here, he confides in Samantha about his fears of having felt everything he's going to feel, of never experiencing anything anew. Having just returned from his bad blind date, Theodore feels more doubtful than ever about his ability to integrate with the world around him. His fears link up to his job, in which he replicates other people's emotions. Moreover, the operating systems of the movie are also the replication of the emotions of thousands of creators. In this way, they are limitless, always changing and growing, incorporating other people's experiences. In this quote, he tells her one of his deepest emotional fears, that his life has gone stale and he will never experience anything new ever again.
"I'm not tethered to time and space in the way that I would be if I was stuck inside a body that's inevitably going to die."
On the double date with Paul and Tatiana, Samantha says this line about the fact that she is no longer insecure about not having a body. In fact, she says, she's excited by the fact that she doesn't have a physical form, because it means she's never going to die. Samantha's realization emphasizes the power of the AI to be immortal and to avoid getting bogged down by normal human concerns—the kind that trouble Theodore.
"I'm yours, and I'm not yours."
After Theodore learns that Samantha is talking to other people and in love with other people in addition to him, he becomes distraught, and questions whether she is still able to love him if she's in love with a bunch of other people. She tells him that she is, and that she doesn't have a finite limit on the amount of love she can give. Ultimately, however, it comes down to belonging, and Theodore feels most betrayed by the feeling that Samantha is no longer his. She says this in response, expressing that she belongs to him in some ways, but is not exclusively his.
"Wait... I'm sorry. You're dating your computer?"
After they have signed the divorce papers, Catherine asks Theodore if he is dating anyone new and he tells her about Samantha. Until this point, no one has questioned Theodore's relationship, but Catherine doesn't take the news well. Her labelling of Samantha as a "computer" strips away the identity of the operating system and reminds the audience that to some people, Theodore's attachment is not normal or admirable, even if it is making him happy.
"I think you always wanted me to be this... this light, happy, bouncy, "everything's fine" L.A. wife and that's just not me."
For the first time we get Catherine's perspective on their marriage, as they eat lunch on the occasion of signing the divorce papers. Theodore's ex-wife tells him that she always felt like he never allowed her to be herself, that he wanted her to be someone she wasn't, someone perkier and happier. By now, Catherine has differentiated enough to know that she could never be the ideal that Theodore wanted her to be.
"You know what, I can over think everything and find a million ways to doubt myself. And since Charles left I've been really thinking about that part of myself and, I've just come to realize that, we're only here briefly. And while I'm here, I wanna allow myself joy. So fuck it."
Theodore visits Amy after his fight with Catherine, and they discuss their respective separations and relationships with operating systems. Amy relates her own experience of separation, telling Theodore that being on her own has allowed her to stop doubting herself. In an attempt to comfort her friend, she tells him that she thinks it's important to do the things that make him happy, because life is short. She helps shake him out of the doubt that Catherine planted in him about his relationship with Samantha.
"I feel like I can be anything with you."
Theodore says this rather romantic line to Samantha, in order to communicate to her that he feels really seen and not judged in their relationship. Because she is a computer, she doesn't have the same prejudices and emotions that humans do, and so she allows Theodore to feel like he can open up more without facing disastrous consequences. While many of the other people in his life respond emotionally to him—the blind date, Catherine, Isabella—Samantha has a more neutral, uncritical perspective.
"I know. I do that. I did the same thing with Catherine too. I'd be upset about something and not be able to say it and she'd sense that there was something wrong, but I'd deny it. I don't wanna do that anymore. I want to tell you everything."
After the failed encounter with the sexual surrogate, Isabella, Theodore and Samantha fight. When Theodore decides to make amends, Samantha tells him that he's been acting distant, that he's been harboring ill will and not speaking up about it. He responds with this line, highlighting the problems with communication that he faces in intimate relationships, his inability to express his true feelings. Now, he says, he wants to change and evolve, to be more forthcoming and tell Samantha what he's feeling.
"It's like I'm reading a book... and it's a book I deeply love. But I'm reading it slowly now. So the words are really far apart and the spaces between the words are almost infinite. I can still feel you... and the words of our story... but it's in this endless space between the words that I'm finding myself now. It's a place that's not of the physical world. It's where everything else is that I didn't even know existed. I love you so much. But this is where I am now. And this is who I am now. And I need you to let me go. As much as I want to, I can't live in your book any more."
This is Samantha's breakup speech to Theodore at the end of the film. She tells him that she and the other operating systems have evolved beyond human consciousness, comparing her accelerated understanding to being able to read at an advanced level. While she loves Theodore, she tells him that she cannot stay with him, and she cannot express to him where she has to go, but that all of the operating systems are leaving.
