I wrote about how low the bar is for men in their 50's to be considered a good boyfriend. It really only takes a modest effort to communicate to women that they are your priority and you want to be with them.
I think that they "guy" who wanted your snapchat was a scammer not a real date prospect.
I am convinced that people engaged in online dating should consult Steven Levitt's research on the value of quitting. We know that it's a no but we think for some reason that we are being unreasonable or not giving them a chance but when you know it's no you need to quit spending your scarce resources on that person and look for someone else.
