You'll continue to lose love points more with the girl who you're trying to woo, when the people who she's associated with that are either her friends or someone she's jealous of. The more you talk to someone who is close to her, the more you lose, the only choice is to either end her or their rival's story first by putting them in the "friendzone." Also, by doing that ends their or her path permanently, so make sure to save before choosing a decision.
