If you had full access to a love rival life would you feel entitled?

If you had full access to a girl entire life who you saw as a threat because you both liked the same guy in school would you feel like you had the advantage against her because you would be able to see her wardrobe and people deemed her as evil in the past? Or would you want a fair fight against her? To get your lover in the end.
