My experience of modern dating has been that it's pretty surreal. There are rules and codes and languages to learn in order to navigate it.There is also, somehow simultaneously, both way too much and not nearly enough filtering of what people put out there about themselves.
I was told over and over that I couldn't do online dating - or, really, modern life - without one. What I also come to learn is what a good friend of mine said about online dating..
People who are active on dating sites, but won't be back in the country for another 11 months.
People who want to meet you for an expensive dinner out without bothering to even ask your name.
ETA: In addition, it's hard "seeing" all the perfect little families on Facebook, etc., but you're going through divorce, single parenting, etc.
It's hard not to compare, even if you know in you're head that only the good stuff is put out there in social media.
