I just had a blind date with a woman. She may have arrived home by now. What should I say when texting?

If you are confident enough to think that you have passed the test in front of her, she has a little affection for you. Generally speaking, being able to date shows that she is still looking forward to finding someone. Then what you have to do now is not to take the initiative to find her, but to let her guess what you are thinking, but don't expect her to take the initiative to find you, which is unlikely. If you really take the initiative to find you, then your blind date is really successful. Otherwise, go to her every other day or two.
