No, he did not. He loved Padmé too much to cheat on her. He even got angry and almost killed Padmé's colleague, Rush Clovis, when Anakin walked in on Clovis trying to kiss Padmé. In addition, he killed innocent children and lost his dreams for her.
However, when they next met in Star Wars: Episode II – Attack of the Clones, Anakin and Padmé's feelings for one another grew into something resembling love, and their wedding at the end of the film solidified their relationship as one of the most important romances in Star Wars history.
Anakin really cared for Padme, both in the Clone Wars show and the movies. For all his faults, he was a man of virtue and when he got attached to someone, he almost never could let go. There was really no reason why Padme should suspect anything, let alone if she thought he didn't love her.
In 'The Phantom Menace' (set in 32 BBY) Anakin is aged 9 and Padmé is 14. He turns ten during the film. By the time of their (sexual) relationship in Attack of the Clones, (set ten years later, set in 22 BBY) he was 19 and she was 24. The name resonated in young Anakin's heart and soul.
The film doesn't flinch away from how horrific that act is, especially as it begins the downward spiral of Padme's death. Nonetheless, as she dies, Padme tells Obi-Wan that there is still good in Anakin. Even something as heinous as that couldn't fully break her love for Anakin.
Yes, his entire character since then was a self loathing tragic monster who has little reason to care about anything. Betraying Mace Windu instantly made him regret his act of impulse, Padme's death and rejection of his actions later on made it stick.
Did Anakin regret choking Padme? Oh yeah. He pushed the memories out of his mind for a couple of decades. But after he faced his son, Luke, in Empire Strikes Back, it was all he could think about.
Despite their growing attraction, Amidala did not believe that she could be with her Jedi protector; Amidala was a prominent senator, and Skywalker was required to follow the Jedi Code, which forbid attachments like romance.
There is no evidence that Obi-Wan and Padme had an affair, and it is highly unlikely given their close relationship. They were friends from childhood, and they had a deep mutual respect for each other.
Padmé was born in 46 BBY (Before the Battle of Yavin) and Anakin's miraculous Force-created birth came in 41 BBY, so Padmé is five years older than him.
At least partially, Padmé is experiencing a kind of Stockholm Syndrome or more specifically, the idea of equating affection with crime, a disorder known as hybristophilia. Anakin confesses his crime of killing the Sand People to Padmé, and later, she totally tells him she loves him.
Every time she speaks, he remembers Padmé. Fighting alongside Sabé reminds him of fighting alongside his wife. While that is certainly painful enough, it's also reminds Vader of the man he used to be, a past he had long ago attempted to kill and bury. However, the memory of Padmé via Sabé won't let his past stay there.
Padmé was well aware that Anakin had committed dark crimes that would've started his fall to the dark side. He even confessed to her that he had massacred an entire Tusken Raider village to avenge his mother, leaving no one alive.
Letting her go just might have saved her life and the Jedi Order. So, clearly, Anakin never actually loved Padmé. He was simply afraid of being alone and losing the one that loved him, and that is only greed, attachment and selfishness, not love. Yoda was right all along: Anakin's fear led him to the Dark Side.
Anakin's Force Choke begins the series of injuries that ultimately leads to Padme's death, and convinces Obi-Wan to fight him. Despite this, when Anakin learns of Padme's death, his immediate reaction of grief and regret shatters everything in the lab with a powerful force shockwave.
She knew he was volatile and even murderous after he slaughtered the Tusken Raiders. As such, the only reasonable explanation for her marrying Anakin is that she was truly in love with him.
He knows it's Anakin, and the events in this week's episode of The Clone Wars, "A Distant Echo," prove it. And I think Padmé is savvy enough of a political operator to let people think that Clovis could have been the person who fathered the child, if only to avert suspicion from her relationship with Anakin.
Jedi Masters Obi-Wan Kenobi and Yoda watched Amidala's funeral from Senator Bail Organa's starship, the Sundered Heart. They didn't want to take the risk to come any closer and be found by the Empire, as they were certain that Emperor Palpatine's attention would be fixed on the funeral.
To hide the birth of her twins from both Darth Vader and more importantly Palpatine. The fact that Amidala had given birth to twins was a secret known only to a few after her death. The mortician Commodex Tahn used a hologram to make her still appear pregnant during her funeral.
Anakin Skywalker turned into Darth Vader because of his attachment to Padmé Amidala. Anakin was always someone who couldn't let go of his attachments in life, and his fear of losing them eventually forced him to seek the power of the dark side to save them from death.
The Jedi Order did not permit Jedi to marry due to a prohibition on possessive attachment that could lead to the dark side and on Chandrila many got married at the age of fifteen.
Yes, when Darth Vader turned back to Anakin Skywalker and sacrifice himself to save his son, he dies and Obi-Wan uses the force to connect with Anakin's spirit. In that time Anakin apologizes to Obi-Wan, desperately asking him to forgive him for everything he has done to him and everybody over the years.
Padme Amidala
Padme Amidala's secret marriage with Anakin Skywalker was one of the biggest reasons he eventually turned to the dark side. His emotions and love for her often clouded his judgment, and sometimes led him to be violent.
It's clear that Darth Vader wishes that Padmé joined him so that they could have remained together. But there are moments in Marvel's other Darth Vader series that suggest that, while the Sith Lord is very much still obsessed with the idea of Padmé, her betrayal may have caused him to think ill of his late wife.
Originally Answered: After Padme died why did Anakin choose to stay on the dark side? The only reason why Anakin joined the dark side in the first place was to save Padme from dying during her pregnancy. He had no choice after the events of Episode III. He had lost his wife and his friends/comrades in the Jedi Order.
