Hrm, well to give you ideas for you I'd really need to know more about you, so these are just things I would super duper enjoy:
1. Make dinner together, then curl up together and watch a movie or binge on a TV series you both like.
2. Game night, whether board or video. Can incorporate dinner making into this too.
3. Check local event schedules out. Not sure what your city has, but my city is poppin' with events (especially in the summer) despite not being a huge city, just touristy, and they're usually not expensive or are free.
4. Go look at antiques or museums or maybe some touristy things in a nearby city (or even in your current city if you never have).
5. Bonfire or some alternative you can manage under the stars, make s'mores or other camping/bonfire foods. Hike or explore wilderness if that's your thing.

I'm boring and simple, I know. But to me these would be awesome dates preferred over expensive "dinner and movie" types. Sorry if someone else said them already, I only skimmed a few posts before posting myself.
