That having sent photos to potential date ..

[shyjenny]

That he would comment on them?
Or at least say something??

I'm new to this dating game and did not post photos on my profile.

I got chatting to a man .. we're both 50... and we arranged a date for this weekend.
We've continued to exchanged messages and getting on as well as one can via WhatsApp since, but he hasn't acknowledged me sending them.

What are your thoughts on this?

Acknowledgment would be fine @whatausername

Because of this…

It was a question @Cheeseandpickleplease

Yeah, he's just not that in to you. Move on immediately and don't waste your time continuing to text. Also, pop a photo of yourself on your dating profile so people attracted to you already will message you.

Neither. Unless you're stunning or ugly you're pretty much what he expected. I suspect you're a well groomed 7/10, which is a 6/10 if you factor in all the younger women....so average. Did you comment on his pics? Was he a little bit grey/thinning with a dad bod? No handsome, not ugly. Probably needs glasses to read the menu? So exactly as you expected.
He wants to meet you though, so go. You can bring up the pics on your date if you like

He's been texting this evening confirming the date.

Online dating may not be the best avenue for you

I second this. You are coming across naive at best, insecure at worst - or as a PP said a bit nuts.
Online dating is not for you.

Must admit though, the fact he swiped without seeing your photo is strange and suggests he's not very picky.
