I posted this (link below) a few days ago after I had a date that went well but I walked out on because he didn't pay/offer to pay etc. https://www.reddit.com/r/FemaleDatingStrategy/comments/etkwkz/just_when_i_was_starting_to_change_my_mind/
Couple of hours after posting it, I got a call from the guy that apparently he saw the post on reddit (weirdest coincidence ever since this didn't get that many upvotes or anything). He explained he didn't realise the etiquette since this is his first date after a break up. I understood since I'm also new to dating (especially OLD) after having long term relationships that blossomed from being friends first. After talking it out, he did say now that he knows this he'll pay next time we go out & I decided to agree to that since the rest of the date went so well. This was all friday (the date and the phone call) and I haven't heard from him since.

I feel stupid for even picking up the phone since he obviously had no interest in continuing to see me and has made no contact. What should I have done differently?
