From my personal experience, you do need a little time, after a relationship, to yourself.
If I wait too long, she may have found another guy already that beat me to it!! I want to balance it with showing interest but not coming off too strong. (Most girls like the guy to show interest first and make the first move.) And its much better to come off strong than to show disinterest. (Text messages are too impersonal, it has to be a phone call.) Ask her to do something with you tomorrow (or whenever is most convinient for her).
One very important part of a healthy relationship is giving each other space.
While it’s important to spend time together and get to know each other, you each need time apart.
Your partner does not need to know where you are or what you are doing every moment of the day.
You each need to respect the other’s privacy and needs.
