How long shall i wait

Don’t be a simp… women are wired differently. You should focus on you and other women… if she is really interested and not “occupied” she will reach out again … for sure.

Don't call or message her for at least 3 days and if she doesn't react by then you know where you stand with her there should always be a balance in the communication.

Try Not Calling or Messaging See How That Goes
That's How My Dad Got My Mom :)
