I can provide some general insights based on common social cues.
When someone says, "yeah for sure" in response to being asked out, it typically indicates a positive response. It suggests that the person is open to the idea and willing to go out with you. However, keep in mind that people's communication styles can vary, and "yeah for sure" might not always be an enthusiastic or definitive response.
To better gauge her interest, pay attention to other non-verbal cues and follow-up interactions. Does she seem excited when discussing potential plans? Does she actively participate in making arrangements? These signs could give you a better sense of whether she genuinely wants to go out with you.
Remember, everyone communicates differently, and some individuals might use neutral or ambiguous language even when they are genuinely interested. It's essential to be respectful and considerate when pursuing a romantic interest and to pay attention to both verbal and non-verbal cues to understand how the other person feels. If you're uncertain, try having an open and honest conversation to clarify her intentions and feelings.
