tell her you enjoy chatting with her and see if she can check in more or give you another outlet.
Message them. Ask to exchange numbers?
Continue to wait. I see no other option really.
look for alternative friends while hoping for a message from the one whose message you seek
Try to find someone new to talk to. :)
They don't like you. Py using a different profile ....
well she is either indisposed or just has no interest
Keep on waiting. Or find someone else to talk to.
