I've been on my first date ever and it went really well, at least way better than I expected. After the date I messaged her saying that I really enjoyed it and that we should do this again to which she agreed. I then asked her if she was fine with going out this Thursday and she said that she had something to do that day so she couldn't make it but suggested that we do it next week when we are both free, which is a green flag from what I've read and learned from here. My question is what do I do until then? Do I keep messaging her(and what do I even text her?), or do I just discuss details with her one or two days before we meet again?
