Well, some people might see things different than you do, and it’s always possible to learn something new by listening to them. But you seem to think you’ve got it all figured out and you have nothing to learn from others. So yeah, a part of your dating problems might come from that.
That being said, it’s crazy that some people give so much importance to money in looking for a romantic partner. I mean, past 30 you should be somehow financially independent… going on a date with the expectation of meeting someone who could raise your standard of living sounds like something from the 19th century.
