Why does dating in LA suck so bad?

I cannot for the life of me figure out how to make a real connection here. I got out of a long relationship about a year ago and since then, dating has been soul-crushing. I have dates that are nice, the conversation is going well, we’re laughing and getting to know each other, then when you follow up for a second date they tell me they “weren’t feeling a romantic connection”. Or even worse, they say “ok, gotta go, bye!” after like an hour and a half and I never hear from them again. One of those two things has happened every date Ive gone on since my break up (4 dates in total, which isn’t a lot but it’s consistent enough to make me feel like I’m going crazy). I get it if the date was a total dud, but from my perspective, it’s usually not! I’m pretty friendly and outgoing, so I don’t find it difficult to get along with people and have a fun time on a first date!

I’ve dated in other places and I’ve never experienced this before. Unless it’s a total dud, it usually leads to a second date. It seems that people are expecting fireworks and extreme passion on a first date, but I don’t know how reasonable that is, it’s pretty rare that I feel that strongly about someone without knowing them better! It’s very possible that I’m doing something wrong, but it also feels very LA-specific.

Mostly just a rant, but advice or encouraging words would be appreciated. Is this a me problem? Or is it an LA problem??

(Edit: I am 25F, moderately attractive, and I date both girls and guys. I’m not a guy lol)
