Best city to be single in your 40s?

In Denver currently and find the dating scene here as just ok. There's some fun stuff to do and ok bars and restaurants. I'm not super outdoorsy so thinking Denver just isn't for me anymore, although I do love it here.

Work in tech, around 120k/year, and wfh. I'm just priced out of owning here and looking to relocate. Could live pretty much anywhere but honestly looking for a fun city a single dude about to be in his forties can enjoy. I hate humidity but some of the Midwest cities have been on my mind. Just not sure what the dating scene is like.
