Most Helpful Guy
On free dating sites, a lot of the people are just there to flirt, not actually date.
People who actually want a relationship - whether on a free or paid site - if they are desireable, do not stop looking because they have a date.
Guys need to ask out 10-20 women a day to get any value out of these sites. They're hoping maybe one of those goes on a first date. That means though they are setting up multiple first dates a week.
A first date is like a job interview. You don't stop looking for work, and the company doesn't stop looking, because an interview is scheduled.
He's interested in meeting you, but he's also aware that every first date is a long shot to go anywhere.
