Padme & Archie
If Anakin had taken Padme's advice about their relationship (well at first), Luke and Leia might never have existed. On one hand, it might have saved Anakin from opening himself up to that much emotion and feeling which was always a dangerous path for a Jedi to tread. At the same time, she knew she would have missed out on the opportunity to be with the man she loved...even if it had taken a life threatening situation to bring it out of her. Even if during all of that, her injuries had caused him to loose focus and run to her.
"I think that might certainly be true in more than one aspect," Padme replied, nodding. "In some cases, if he followed my advice, things might have been better, but I could very well have not ended up with my beautiful children or with the man I love." In that regard, she could take the bad that had happened all over again...even her death.
At the comment, Padme laughed lightly. "It's more than okay. I just...most people go more starry-eyed for my husband, son, or daughter," she added. "But as for love, yes, I believe it does conquer all in the end."
