Last Wednesday this conversation happened:

"Hey are you doing anything on Sunday"

"I have a study session with my teacher from 12-4."

"Ah"

"Yeah but people usually don't stay for the whole thing"

"We should do something then."

"Okay"

She didn't contact me over the weekend, so I texted today:

"What happened to sunday"

She replies "What was on sunday"

At this point I think I have several options:

1. Call her out for faking that she forgot

• "Lol did you already forget" or "Come on now, you remember"

2. Remind her what I said

• "Remember what we talked about last class" or "We talked about hanging out then"

3. Trust that she forgot & ask her out again over text today, or in person (next time I see her will likely be thursday)

4. Ignore and ghost

I'm 95% sure that she is somewhat interested as she has sent many signals over the past month. But if she really were, then it seems really unlikely that she has forgotten by now. How should I go about this?
