I was sure I wouldn't regret it later, and that losing so much would be worth it in the end. Guess I was wrong.
James was one of my best friends, and I was rather fond of Lily too, but I had to sacrifice them to get what I really wanted at the time. Of course, that would mean losing Sirius and Remus too when they found out, but it would still be worth it. I would be safe, and I would have the love I only ever dreamed of.
James would have understood. That's how I convinced myself I was making the right choice.
She was there when I told the Dark Lord where the Potters were. She was impressed that they actually used me as their Secret-Keeper. Yes, that was one of the best moments of my miserable life, when Bellatrix Lestrange was impressed by the likes of me.
I thought I had her then. She had told me that she could only love me if I did something extraordinary as handing the Potters to the Dark Lord. Well, I did it. So why wouldn't she love me now?
"Bella," I said to her right before we left for our homes, "you know I love you."
She simply said, "Yes," and waited for me to carry on.
"Well…I've done it. I've handed the Potters to the Dark Lord. You said you'd love me then. Bella…"
I trailed off, but she didn't notice for laughing too hard.
"You thought I was serious? Oh, Wormtail, you are a fool. You'd be great for birthday parties…"
And with that, she Disapparated, and left me to watch my heart turn to ashes and my world to dust.
I never stopped loving her, but I regretted it. I regretted the whole thing until the day I died.
A/N: Yes, I was bored. And I might actually be insane. I just like to experiment with random couples, and I like to think that Wormtail eventually regretted his betrayal.
