Dates should help you get to know each other. They should be things you already enjoy doing, or places you like to go, or want to see if you like. Expressions of who you are.

Asking the AI at all is a large part of the problem because it screams you have no personality and no preferences and think dating is some Hollywood romcom style big showy thing that it's not and shouldn't be. Every happily married couple I know goes on simple dates and always has. You shouldn't need a list of date ideas. Period.

My wife and I went to her favourite restaurant for our first date, our most recent date was walking through a bookstore and showing each other fun covers. One of my best friends, his first date with his wife was just hanging out at a local park eating sandwiches and their most recent date was learning to make pierogi together. Things we enjoy or they enjoy. (Married about ten years for reference) Every happy couple I know has similar stories no matter how long they've been together. Even my 22 year old cousin.

If you need a list of date ideas. Just write down the stuff you like to do, or want to try. Done.

Anything bigger should be a special thing with someone and it should be special to you and your partner and looking for a list of other people's ideas is the wrong move.
