So, I asked this girl I’m doing a project with to come to college tomorrow at 12. She said that she doesn’t come to college on Fridays.

Should I still persist and tell her to come (hold my frame/be strong) or just reply that we can meet on another day?

This can be generalised to other cases too. For example, asking a girl out for coffee or a movie.

My question is at what point should I back off and tell her that we can meet at another time?

If she doesn’t want to meet me at the time I said, and if I said that it’s alright and that we can meet another day, does it make me look weak?
