I can offer some general insights into why someone, in this case, a girl, might confront you about your feelings for her:
Clarity and Communication: Sometimes, when a person senses that someone might have feelings for them, they may want to clarify the situation to avoid any confusion. Open communication can be healthy in any relationship or potential romantic interest.
Reciprocation: She might have feelings for you too and wants to see if you feel the same way. By initiating a conversation, she could be trying to gauge your interest in her.
Friendship: It's also possible that she values your friendship and wants to address any potential romantic feelings to make sure it doesn't jeopardize the friendship.
Curiosity: People are naturally curious about how others feel about them. She might be curious to know if you have any romantic feelings towards her.
Concern: If she suspects that you have feelings for her but hasn't reciprocated those feelings, she might want to address it to ensure that both of you are on the same page and avoid leading you on unintentionally.
As for whether she's "just playing," it's essential to consider the context of your relationship and her behavior to make a judgment. Some people might use confrontation or questioning as a way to manipulate or tease others, but it's not fair to assume this without more information. Trust your instincts, and if you're unsure about her intentions, the best approach is to have an open and honest conversation with her to understand her motivations better.
Remember, communication is key in any relationship, and discussing your feelings openly and respectfully can lead to a clearer understanding of each other's intentions and desires.
