I wouldn’t describe my experience with online dating as a nightmare, but I will say that it’s been wholly unsuccessful. The one time I thought it had really worked out for me ended when he discovered his previous girlfriend was pregnant. (OK, that does sound like a nightmare.)
I get along with men really well and I have made some new friendships with men I met online with the intention of dating them. The algorithms used for online dating are pretty good when it comes to compatibility, they just cannot predict attraction, which is key to starting a new relationship online when you don’t have the luxury of getting to know someone over time. Where dating apps have succeeded with efficiency, it’s the same reason they continue to fail in efficacy.
