Why do you think that? Nothing really matters until you meet up in person and once you do, how you planned it doesn't really matter. It isn't some backpage transaction, there isn't any commitment or investment before you meet up. If you want to leave you leave.
The 'fast-food of realtionships' sums it up pretty well. However, if you disagree and have found otherwise then I respect that too.
Personally, it's not for me but then I have been single for a while so I'm not really qualified to criticise.
Again, you are just saying the same thing but not actually explaining why you are saying that.
