Hi JasonArk,
You shouldn’t keep waiting on her to initiate another text conversation, you should text her.
After the last time that she initiated a text conversation with you, she may have been hoping that you would follow that up by initiating a text conversation with her the next time around.
So far, you haven’t done that and it is unlikely that she will try to initiate another text conversation with you.
You don’t really know how long school will remain closed.
It is best to keep in touch with her as often as you can while the both of you are currently under quarantine and having to study online.
This way, you can build rapport and momentum with her.
This could then lead to the both of you mutually wanting to go out on an official date when the quarantine is over.
