One thing I read on IG that one couple decided to do in NL was what they call "stoepen" ("stoep" is the Dutch word for sidewalk). They'd get some chairs to their front yard, which is connected to the sidewalk, and they'd greet people and start chatting with them. When vibes clicked they'd invite them to come sit with them, until people got in the habit of sometimes coming by and sitting with them.
So there's that. Obviously there are other ways, but thought it'd be fun to share.
Also research on self-disclosure might help. Long story short: be the first to reveal some details about yourself and progressively go deeper to the level that you want, it's kind of a tit for tat type of thing. There was one popular article about it so you could "fall in love" but IMO it's not love, it's simply building a deeper connection. Check it out [1].
I used to be really interested in topics like this, so if you want to know more about it or brainstorm, feel free to reach out. My email is in my profile.
