Hi Paisley,
What you are missing is that there are lots of men on dating sites and apps who swipe right on almost every potential match they receive. They do this to play the numbers game and increase the odds of getting matches.
They are not necessarily going to initiate a first message to every match they receive. Oftentimes, they will pick and choose who they decide to message upon matching with them. If they don’t find the dating profile of a woman who matched with them all that appealing, they don’t always feel the need to message her first.
They are more concerned with getting matched with women that they are the most attracted to. Those are the matches that they will initiate first messages to.
They will leave the less desirable match to her own devices. If she chooses to send a first message to them, fine. They may or may not respond to it.
If she doesn’t send them a first message, they will only come back to her and initiate a first message if they aren’t getting as many matches as they were hoping to get from more attractive women.
