Even though she believes that all she is doing on dating sites is talking to people, she is exposing herself to constant temptation.
In telling you that her only motivation in being on dating sites is to “just talk” to people, she absolves herself from the idea that what she is doing is inappropriate.
The guys she talks to on dating sites aren’t of the same mind.
Considering she is on a dating site, this isn’t all that surprisingly.
A guy on a dating site that keeps emailing you without asking you out on a date isn’t serious about meeting you.
No matter how good the email conversations have been, you are wasting your time if this guy has been talking to you for multiple weeks and hasn’t asked you to meet in person.
