The popular TV show The Vampire Diaries ran for eight seasons, so it had plenty of time to introduce and build multiple couples. Yet these of them stand out for the rest - Elena and Stefan, and Elena and Damon. Elena and Stefan were the first big couple of the show and they got together shortly after Stefan had returned back to Mystic Falls. Their relationship was far from ideal, considering all the supernatural threats they faced, but they still loved each other.

However, that doesn't mean they were always kind to each other, and during their relationship and even after, both Stefan and Elena had done some pretty bad things to each other.

Elena Did To Stefan: She Was Jealous Of Him

Considering the big picture, jealousy doesn't seem like such a big deal. Except, in this case, Elena almost committed two murders because of it. While her emotions were switched off, she still got jealous when she saw Stefan and Caroline having fun together at a party she threw.

So she first threatened Caroline's mom Liz, and then fought Caroline in the woods and would have killed her if Damon and Stefan hadn't stopped her.

Stefan Did To Elena: He Lied To Her About Katherine

Stefan and Katherine have a complicated relationship in the show. He was madly in love with her once, but hated her when he turned into a vampire.

Yet despite all the problems it could have brought, Stefan should have been honest with Elena and told her the truth about Katherine and that she looked exactly like Elena. Honesty is important in every relationship, but Stefan apparently didn't get the memo.

Elena Did To Stefan: She Drank Damon's Blood

When Elena changes into a vampire in the fourth season, she struggles with her new life, most of all her urge to drink blood. Vampires have to feed but Elena has trouble keeping the blood in. To help her, Damon offers her to drink his blood and Elena accepts even though she and Stefan are still together at the time.

Feeding on another vampire is very intimate, so it's a bit like Elena cheated on Stefan. To be fair, she didn't know about the implications, so it wasn't entirely her fault.

Stefan Did To Elena: He Kidnapped Her To Get Back At Klaus

When Klaus finally releases Stefan from the obligation to fulfill his every whim, Stefan decides to get revenge on Klaus for ruining his relationship with Elena and making him leave Mystic Falls. He steals the coffins in which Klaus stores his siblings, kills some of his hybrids... oh, and he also kidnaps Elena.

He then threatens to drive her off the Wickery Bridge even though he knows it's the same bridge Elena's parents drove off and died. Not only does he scare Elena when he says he'll change her into a vampire, but he also reminds her of her parents' death.

Elena Did To Stefan: She Let Him Drown All Summer

Other The Vampire Diaries characters claim that Elena is a great friend, but the evidence actually points out to the opposite. Not only did she try to kill both of her best friends, but she also didn't notice it when Stefan disappeared. Neither Damon nor Elena noticed that Stefan had vanished for the entire summer.

Yes, he told them he was leaving, but Elena still didn't try to call him, not once, to see how he was doing, since she was so obsessed with Damon at the time. And as a result, Stefan spent the whole summer locked in a metal box (courtesy of Silas) and kept drowning over and over again.

Stefan Did To Elena: He Endangered Her Life

Elena's and Stefan's relationship had its ups and downs, but it mostly seemed happy, at least when it lasted. However, there's no denying that simply by inserting himself into Elena's life, Stefan brought her in danger.

Both Stefan and Damon have a knack for attracting troubles, and it wasn't fair of Stefan to bring all of the vampire/supernatural drama into Elena's young life, especially since she was still dealing with her parents' death at the time and was emotionally vulnerable.

Elena Did To Stefan: She Kissed Damon

Once Elena and Stefan broke up, she was free to kiss whoever she wanted - including Stefan's brother. But what some fans might have already forgotten, Elena actually kissed Damon several times while she was still in a relationship with Stefan - sort of, anyway.

For example, she and Damon shared a kiss in the third season while Elena was still looking for a way to bring Stefan home and free him from the influence Klaus had over him.

Stefan Did To Elena: He Didn't Accompany Her To The Miss Mystic Falls Contest

During the first season of the show, Stefan fell off the wagon and he had trouble controlling his lust after human blood. At one point, he was due to accompany Elena to the Miss Mystic Falls contest.

They were supposed to dance together, but Stefan instead attacked one of the girls competing in the contest and bailed on Elena, even though the contest used to mean a lot for Elena's mom and Elena herself cared about it. Luckily for Elena, Damon stepped in and replaced his younger brother during the dance.

Elena Did To Stefan: She Slept With Damon Shortly After They Broke Up

Damon and Elena share a close dance in The Vampire Diaries.

Stefan and Elena formed a couple, more or less, in the first three seasons of the show. Stefan then broke up with Elena at the beginning of the fourth season because he came to realize that she had feelings for Damon.

It's true that it was Stefan who initiated the break-up, and not Elena, but she still behaved less than admirably when she slept with Damon only a single day after the break-up. Waiting a bit longer to uphold the decorum wouldn't hurt her, but no, Elena just didn't wait and went for it straight away.

Stefan Did To Elena: He Drank Her Blood

Drinking blood is necessary for vampires, but unless they're drowning deep in the blood lust, they can choose how they're going to feed - whether from animals or from people, from those who are willing or someone they'll force.

Stefan had fed on Elena multiple times, but she didn't always give him her permission, and that should be a big no in a romantic relationship.
