I went on a first date yesterday and it went great. She said she had a great time, and we agreed to have a second date on Sunday. I sent her a text this morning saying how great yesterday was and looking forward to seeing her on Sunday, and she replied saying she is looking forward to Sunday. Should there be any more conversations between is before the second date?
Since Sunday is only a couple of days away, just hold out and talk to her then. As a woman, I find it very much a turn off when a guy suddenly is all in my life (ie contacting me daily or every other day).
Don't talk to her again until the day before and on the day before you should just confirm your plans with her are still good to go. Don't force yourself into a boring texting conversation or something when you don't have to do that. A little space is good and shows that you are independent and not a clingy person, which is a great sign.
