You keep running into the stereotypical "date", which is a dinner and sometimes includes a movie. You actually can do better with just like "hey I've been wanting to try bouldering at this rock climbing gym, want to check it out together?" Or similar. Don't think in terms of dinner dates. Think in terms of activities you would like to do with your significant other long term. My wife and I currently take adult gymnastics classes and almost never go out to dinner.
