This is something I’ve noticed a lot recently. I’ve been on dates with 4 people this year (some more than others) and out of them I would say only one showed genuine interest and asked me about my life - and these are the dates I enjoyed the most - because inherently, we like talking about ourselves!
2 of the guys I distinctly made an effort on our second/third dates to not just pepper them with questions about them (my go to on first dates if all else fails, ask them about themselves) and even then they still didn’t step up. I also, like you, noticed they wouldn’t even ask the basic “and what about you” in response to my questions. I ended up knowing everything about their families, jobs, interests etc and they probably couldn’t even tell you what I did for a living.
These are the ones that were then super keen to meet up again and carry on! Yes I bet you are darling, you’ve just talked about yourself and had an ego trip for the last 3 hours!
It’s disheartening isn’t it. For you, I would meet him again and see if he steps up when you purposefully don’t lead the conversation with facts about him. It’s hard because for me, I want the conversation to flow, but I’m not here to just give you an ego boost!
