When you asked this girl out in person and she said yes, she was in the moment.
In fact, it isn’t out of the question that she believed it at the time.
At that moment in time, it felt right to say yes to you.
Some time later, you sent her a DM to make plans for said date and thus far she hasn’t answered.
It’s no wonder that you are ruminating over whether she is interested or not.
Unfortunately, she isn’t.
A girl that is interested in a guy doesn’t make him wait this long to get a response from her.
She is excited about him and can’t wait to hear from him.
She is daydreaming about what it would be like to go out on the date with him.
Her energy level is high and she is brimming with anticipation.
It’s been a while since you sent her a DM to set up this date.
This doesn’t reflect a high energy level or excitement about you on her part.
This is a reflection of a girl that isn’t interested in going out on the date that you proposed.
Confusing, isn’t it?
After all, you get along with her and she seemed enthusiastic about going out with you.
It’s important that you recognize that a girl can get along with you, say yes to going out on a date with you, and not want to follow through with it in the end.
Girls are socialized to be agreeable.
To this end, she doesn’t want to turn you down to your face.
As aforementioned, there is a probability that she was flirting with the idea of going out with you when you made this request.
But, as often happens, once a girl is no longer in the presence of the guy, she comes to reason.
She has had time away from his influence to ask herself whether she does want to go out on a date with him.
There is no sense of excitement when she thinks about him.
She is not curious to get a deeper insight into who he is as a person.
There is a feeling of discomfort at the thought of sitting across from him on a date.
In these private moments, she determines that she doesn’t want to follow through with the date.
She acknowledges that you don’t cross her mind whenever she parts ways with you, regardless of how friendly her conversations have gone with you in the past.
This means that she isn’t emotionally invested in the idea of a romantic courtship with you.
Her history is her teacher.
Whenever she has ended up dating a guy, she spent countless hours thinking about him beforehand.
She felt a surge of dopamine whenever she did.
This has never happened with you.
To this effect, she comes to a decision that she doesn’t want to go out on a date with you.
Despite saying yes to your request to go out on a date, she was merely caught up in that moment, not wanting to dampen the mood or make you feel bad by telling you no.
Now that she is away from that situation, she knows that she is not interested.
As a consequence, she has chosen not to reply to your DM.
