It's just becoming too frustrating at this point, I'll let her reach out and otherwise move on. It's just super weird behaviour from her side, when we're texting fine, and then I ask if she wants to join me for a meal, and nothing - and then the very next day she tries to come to my office like 3 times, but I was busy, always waving and smiling. What kind of fvcked up behaviour is that? And still no reply, will be two days later.Ok, let's take it step by step.
I don't like using the word "desperate", but are you so desperate to see her again that you can't wait a week?
How about waiting until you see her and then you go up to her with a "Hey, last time was fun, wanna go out for a [insert coffee, drink, movie, a$$f*cking] on [insert day]?"
What can go wrong? She can flake, no problem, forget about her.
Because of low interest/fear.
She might have been bored and was thinking "Hey, why not"
The point is, women want men. Right?
Why not be a man?
