I messaged her

So I messaged her on Monday and apologized she responded back. She said she wasn’t ready to accept my apology at the moment. And then we talked for a little bit caught up. Then yesterday she messaged me in the morning saying she was very stressed and I sent her a message basically saying I know you’ll get through it. You’re strong. And she left me on open I don’t know if that is her way saying she needs more time or what I haven’t sent her a message just because I don’t know what she wants and I don’t want to start anything if she isn’t ready

Any tips on what I should do?
