I number-closed this girl online, she seems pretty into me... we texted for a couple of days... on Sunday I asked her out, she said she did not have her work schedule for the week yet, but she would have it on Monday... so I told her to text me on Monday when she had her schedule and she said "okay, sounds good..."

She never texted me... now it's Tuesday...

how long should I wait before following up, and I would appreciate any advice on direct, but non-needy ways to ask her out again...

I really think that she is into me... I'm just worried about falling into an AFC trap by responding wrong to her not texting me...
