I don't think her marrying James was really a major flaw, because people change. James was a jerk when he was in school, but most people grow out of it, and from all that we know of older James he seemed alright. And plus, Snape wasn't her friend anymore, as the option even stated, so it's not like it was an act of betrayal towards him. She loved James, she married him, no big deal.

I do sort of think that her stubbornness could be considered a flaw, though, especially since I ship Lily/Snape, lol. I know what he said to her was horrible and all, but I still think she would have done well to have forgiven him and seen the good in him.

none of the above. Her flaw was ever becoming friends with greasy Snape in the 1st place.

neither really.

she stopped being friends with Snape, she wasn't friends with Snape when she dated or married James. Snape wasn't good at that time. and yes, Snape loved her, but so did James.

maybe she was stubborn, but hey i'm a Lily&James-shipper, so i have nothing against it.

this one

@r-pattz James did to continue bully Snape in private while eventually before her death Lily forgave Snape so one can argue that Lily was willfully naive in marrying James

She should have been with Snape, they were best friends and he loved her, and I know she cared about him. James was a jerk to Snape and she actually married the man who bullied her best friend. It just doesn't sound right. Yes, people can grow out of somethings. But still I don't remember James saying he was sorry to Snape, all he did was take his best friend away from him.

Your a flaw if you think lily is

being friends with Snape , huge flaw

She married the man who bullied and psychologically damaged her former friend

I.CAN'T.EVEN. Seriously?!? I love how this fandom HATED Snape for the first 6 books and after the 7th one everyone is heads over heels for him! Yes, I get it that he changed, that he looked for redemption, and he was definitely one of the strongest characters in the book, but the unwarranted HATE James get for this is absolutely RIDICULOUS!
I agree that James was a jerk in his early life, but he CHANGED! People grow up and they mature, especially during war times! He redeemed himself, became a better person at 17! He became someone who was GOOD ENOUGH for Lily, who she could fall in love with and spend her entire life with!
Snape on the other hand was willing to sacrifice his relationship with Lily to become a death eater! Even after he called her a mudblood, Lily gave him an ultimatum between her and Voldemort, and he CHOSE Voldemort! He loved her, yes, but he wanted to affiliate himself with Voldemort more! He chose a life path that was the complete opposite of Lily, and he did it with his own free will, no one forced him to join the Death Eaters, it was what he WANTED! And yet you guys believe that he was the right person for Lily?! In what sense?
He changed once Lily's life was in danger! He knew what Voldemort was capable of, and it was then to protect her that he turned, but it was too late by then!
Both James and Snape had to made a decision, they both changed, only difference was that one changed into someone Lily fell in love with and the other into a Death Eater!
I feel sorry for Snape, and I have a lot of respect for him for everything he did after Lily's death, but I see it as his redemption! I can't even imagine the possibility of him and Lily together after everything that happened, and the bashing James get because of this drives me insane! James didn't come in between Lily & Snape, because there never was a Lily AND Snape!
So to me, Lily's biggest flaw was turning a blind eye to everything Snape was doing in their first five years at Hogwarts and still being his friend and defending him! She knew he was in way too deep with the dark arts and she still stuck with him, hoping that her friendship could change him! Lily's heart was made of gold and I don't think she would just hand it out to anyone! And that makes the Lily & James lovestory all the more beautiful and perfect!

neither

I love how people seem to forget how popular Severus was before the seventh book came out.

Also, Lily never gave Severus any ultimatums. Ever.

I don't think either of these are Lily's major flaws (unless we're looking at this from the perspective of one of the characters in the book?)

marrying James is not a flaw

Everyone thinks Lily should have been with Snape just because they read the Prince's Tale! She didn't want to marry Snape, she loved James! So why would it have been better to marry Snape? People said James was a jerk(which he was), but Snape was NOT nice to James either. So I think she did the right thing going with James.

I have to express my entire agreement with every single word othobsessed92 wrote. Lily was right to marry James. It was not a fault. Not Lily's and especially not James's. James was a jerk in his teenage years. He grew up and picked a side to stand up for. For Snape it took Lily's life to grow up and pick a side. Yes, he is a well done character and he definitely had guts, but let's just STOP overrating him. James is as good a person as Snape. And he loved Lily, probably as much as Snape (see, he died to give her a chance). So get the fuck off of James.

James, Lily, and Snape are all fictional characters that we interpret and like based on how the author wrote them.

Especially since James is a minor deceased character we don't know if he ever stop bullying and treated people horribly that he consider beneath him like Snape for instance

THIS.

I might just punch someone in the face for actually putting marrying James as one of Lily's flaws.

I 100% agree with othobsessed92.

Snape chose Voldemort. James chose being a better person.
I just feel like everyone forgot what Harry went through because of Snape. In the Prince's Tale, it's obvious that Snape only cared about Lily and wouldn't mind if James and Harry died. How can you even support that kind of relationship?

Othobsessed92 has summed it up perfectly.
