Something similar happened to me in reverse about 10 years ago. I matched with a guy on Tinder who looked gorgeous in his pictures, and was just my type.
We chatted for a few weeks and even spoke on the phone a couple of times, so before we met in person, I had a really good feeling about him. He had a lovely voice, was very well-spoken, and had a great sense of humour.
I was really excited to meet him for our first date because I felt we had hit it off so well already.
When I walked into the place we were meeting for our date, I actually walked past him and didn’t realise it was him sitting there until he called my name. I played it cool and made some silly excuse for why I didn’t see him, but OMG, he looked nothing like his pictures.
The thing is, he didn’t use filters or augment them in any way. They were all relatively recent and close up, but somehow he had managed to take them at an angle that just made him look completely different. It still baffles me to this day 😂.
Not only did he look different, but the guy was an utter weirdo. The stories I could tell about that creep should feature in some kind of PSA about online dating.
Anyway, all that to say, pictures and even chatting online aren’t always an accurate representation of someone.
In your case, I would go on the date and see how it goes. If you’re still not feeling it, then it’s fine to say so - that’s what dating is for.
There’s obviously a reason you felt inclined to meet him in the first place.
