Ideally, especially in the early stages of your connection, contact her once. Have a great date + short follow up text message after that.
Give her space to miss you + fantasize about what she experienced with you.
Imagination is a powerful tool!
The fact that she does not hear from you or see you physically does not mean that your relationship is not growing!
On the contrary!
She can have a great date with you and spend the rest of the week dreaming about the last romantic kiss you shared.
This is NOT about playing games, ok?
If you text her 3 times a day, email, call, you will quickly appear needy!
If you initiated contact once and she responds. Next time, let HER initiate contact and come up with something fun to do.
