Oh yeah, I gave up on online dating long ago. Barely got a dozen damn matches in 8 months of trying. Just like in real life, women can always do better.
Yeah, I was at that point after a string of failures (I'm actually still friends with two of the girls I met on there) but then I eventually met my wife on there. Can't say it works that way with everyone--times change and that was 13 years ago--but I certainly remember the frustration with online dating.
Hell, ANY form of dating tends to be pretty frustrating.
