I have this canon in which their life was pretty much shit inside that house. They loved Harry to death (literally), but they also hated being inside that house 24/7. James used to be moody when Harry wasn’t around (or when Harry was around too) because he couldn’t see his friends and he couldn’t fight in the war in the way he always dreamt, and that frustrated him. And Lily was irritable, especially when she and James were alone. That last night was like any other night, they ate dinner in silence and even knowing James wasn’t up to it, Lily insisted on having a little “party” in the living room, with sweets and chocolates, but everything was sad and rather quite except for Harry’s giggles while riding his little broom all over the place.

They were selfish and immature and 21 years old, and the first thought when Voldemort made his appearence was of regret. Because they didn’t enjoy the last part of their life and Harry as much as they should have, they didn’t tell each other “I love you” as much as they wanted to, and that was it, no second chances, no more oportunities to fix it, that was the end and both of them couldn’t stop thinking about how they didn’t tell each other “I love you” that day.
