Many years ago before I met my wife I developed a friendship with a young woman I had to speak to over the phone most days at work. We really hit it off and developed quite a bond during these calls. We exchanged home phone numbers and chatted for hours in our free time.
This was long before the Internet so had no idea the other looked like. We sent photos through the post and liked what we saw.
We eventually decided to meet up and really when we did, we both started laughing. No attraction between us at all, not enough connection to want to meet again. In fact I intensely disliked her on sight, I think she felt the same.
I was disappointed, but it could have been very awkward.
You can only know if there is any chemistry by meeting in person and I don't think Internet dating helps. My wife looks nothing like what was my 'ideal woman' and I would have swiped left if I saw her profile on an app.
It was love at first sight for us, a chance meeting in a lonely place.
