I FEEL YOU! The struggle is REAL! That's interesting about the A list--maybe it is slowing down? I heard/read something about how dating sites were making it "too easy" to date and therefore people were not as likely to find meaningful relationships. Basically it boiled down to "you have some idiosyncratic behaviors, rather than deal with you as a whole human being and take your flaws with your best qualities, I'll just go find someone else, there's plenty of fish in the sea--look here are 2,000 other women, I'm sure most of them are perfect for me!"
So people are becoming more fickle in the face of so much variety and getting a lot more selective. Which, yes, definitely be selective! Don't date someone who's bad for you or toxic, but accept that all people have some flaws or issues and some amount of baggage*, and find a way to deal with it instead of just abandoning ship at the merest provocation.
*caveat: except for me I'm perfect! Bwahahahah!
It's just hard, dating is miserable until you find someone you like and who likes you back, and then that's a whole other can of worms!
