James fell in love with Lily from the moment he first saw her on their first train ride. James was especially delighted when they were both sorted into, in James' opinon the best house ever, Gryffindor. James tries to be around Lily whenever possible, having his friends sit near her friends during mealtimes.
James grew up and Lily realized that he wasn't as bad as she'd thought. Also, Lily already sorta fancied him. We see this in two of the memories: In SWM, Lily only yells at James and ignores Sirius even though Sirius was being just as bad.
Sirius says James “deflated his head a bit” in seventh year and that's when Lily goes out with him. It's not just to teach Snape a lesson (though that's what he thought I'm sure) it's been two years. Lily saw James had matured, she gave him a chance. She liked what she saw, and the two fell deeply in love and married.
By James' and Lily's seventh year, James had lost the less savoury aspects of his personality. He was even appointed Head Boy, despite the fact that he had not been a prefect. He also finally managed to impress Lily and the two began dating at this time.
In the Harry Potter series, why didn't Lily marry Snape? The simple answer: She didn't love him. The more complicated answer: He proved again and again that he wasn't willing to listen to Lily, respect her or her views, or love her in a healthy way.
Lily brought light and warmth into Snape's life from the moment they met. He was an isolated, lonely child whose magic would have only made him more of an outsider in his hometown of Cokeworth.
We can therefore presumably safely conclude that Lily was not noticeably pregnant at the time she died.
To be fair, James would (and did) willingly die for Lily too. But Snape loved Lily so much that he was willing to die just to avenge her. He would die just for the memory of her.
And the Dursleys didn't attend the Potters' marriage ceremony. "[Petunia] and Vernon chose not to attend Lily and James' wedding.
They were close friends, she saw in him someone special that she could care about. But she couldn't be with him. So, it seems like it was very unlikely that Lily ever found out Snape loved her.
The reason why the sacrificial protection charm is invoked only when Lily attempts to save Harry, and not when James puts himself between Voldemort and his family, is the specific circumstances of each situation. James is destined to die, as Voldemort never gives him an option to save himself.
One reason Snape doesn't want to reveal his love for Lily is his intensely private nature. Having others sentimentalize his feelings would cheapen them. He also wouldn't want to be object of pity.
Lily and James weren't just parents, they weren't just a young married couple fighting against the darkest wizard of all time — they were also, maybe most significantly, the loves of each other's lives.
A Professor at Hogwarts School of Witchcraft and Wizardry, Snape is hostile to Harry due to his resemblance to his father James Potter, who bullied Snape during their time together at Hogwarts. As the series progresses, Snape's character becomes more layered and enigmatic.
"Lily! After all this time?" he asked and "Always," replied Snape. Snape having the same Patronus, the doe, as Lily symbolized his everlasting love and unwavering devotion towards her. He hadn't stopped loving her after their last altercation, marriage to James Potter, or death.
Peter Pettigrew
James and Lily died not knowing exactly what led to Voldemort finding them, but they knew that Peter was involved, whether voluntarily or unwillingly. Because they trusted him with the Fidelius Charm, they must have believed him a sincere and steadfast friend.
No doubt Petunia would have been saddened by the news of Lily's death but those complicated emotions – grief, regret and unresolved jealousy – were probably buried in the distractions of housework, gossip and pandering to her son Dudley's every whim.
Petunia never showed any love and affection at all towards Harry because he reminded her of Lily and the wizarding world. She treated him as a waste of space, giving him the cupboard under the stairs at first and making him do all the chores. She, along with Vernon, ignored most of Harry's birthdays.
Dear Petunia, It is with great sadness that I must inform you of the death of your sister and her husband. They were murdered by a Dark wizard known as Lord Voldemort, whose cruelty and violence they had been fighting for years. I tried my best to protect them, but, alas, I regret to say that I failed.
Snape loved Lily deeply: through their years at Hogwarts; through her marriage to another wizard, James Potter; through his time as a Death Eater; and long after her murder at the wand of Lord Voldemort.
Dumbledore reveals how thoroughly he loves Harry. Harry is brave, and Dumbledore is proud as any father would be. More than that, Dumbledore succumbs to a parent's weakness; he cares more about Harry's happiness and wellbeing than the wizarding world he is trying to protect.
That's right! You heard me- their daughter. For those unaware, in the Cursed Child (which was written for a POST Harry Potter world)- it's revealed that at one point in time, Bellatrix and Voldemort conceived a child of their own- Delphini.
Bellatrix used a powerful "love potion" on Voldemort and they have sex while he is temporarily obsessed with her. She then uses obliviate on him while he sleeps (you know, he falls asleep after his post-sex cigarette) and tells everyone that the baby is her and her husband's.
In the Cursed Child we find out that Bellatrix and Voldemort had a daughter, which means that Bellatrix would have been pregnant during the books.
