To be honest, since i started doing this, i never got to the point where I have to reach out. Typically they will within the first 3 days. The reason i would reach out after about a week and try to set up a meet is so that if they reject (which i would expect at that point) like say you ask them out and they say they are busy, work, blablabla, then i can tell her cool, hit me up when you are free and forget about her. If she comes back weeks or months later, no date, straight lay up.
to your point the shorter window implies they still have interest.
im not saying you need to be text buddies, but if this is someone you are actually interested in then be assertive and put out a feeler. In this day and age a week of no contact = folks done moved on to the next person. These women aint working on construction sites where they cant have their phone lol. They on their phone 80% of the day.
" within the first 3 days even if they are not feeling you that much, just to keep you as an option.
clock is ticking
just gotta find a way to finesse another low cost night out
