I am the same height as you and now married. 10-15 years ago I came to the conclusion that dating sites and apps are the last places I should try. They encourage people to pre-judge you based on superficial characteristics that you can never win. It's simply not a fair fight. I've found that I stood a better chance in face to face situation: at least then I can display unique characteristics rather than just be a sheet of specs.

My wife also happens to be shorter than me and she has never been on any dating site.
