(Let's say A and B are friends in their late twenties, and A is a pessimist when it comes to dating and relationships.)

A: She only loves you for your money, obviously. If you told her you sold your car and quit your job, she'd be gone in a minute.

B (being sarcastic): Sure, I'll take your word for it. You're a self-proclaimed authority in dating, aren't you? You made me realize that every woman I've ever met or fallen in love with was either a sociopath or a gold digger.

(I got mixed responses the last time I asked native-English speakers if this conversation sounded natural to them. Some said the wording is so archaic and stilted. Others said it's fine the way it is. What are your thoughts? If you were A, and B told you that, would you say "well, I didn't expect a 21st century native English speaker to say that"?)

Without the history between the conversation, it does look like a awkward situation to be in if you try to respond to B.

I mean how many times have you told him or has someone told him that the woman he is with is only after his money.

There is no one way a native english speaker responds or expresses themselves be it in formal or informal writing, or person to person, good friends, or acquaintances. You will get differing opinions depending on the differences of regions and locations of the various styles of native english speakers.

One man's soda is another man's pop. It's complicated. There is no ONE way to talk for english speaking natives. Confusing ain't it? Think of the difference between BRITISH english, and AMERICAN english as an example.

It really depends on who you're asking. It sounds fine to me, and I read a lot of different styles of books, an avid reader. Some I find unnatural in the way they write, but to me, this sounds like a conversation I'd have in the situation they're in. But that doesn't mean everyone will feel the same way.

English has so many different dialects, so many different accents, so many different forms. What do you mean by a native English speaker? They speak English in England, and Australia, Canada and the US, and more. All native English speakers, and all will use very different ways to communicate.

**You made me realize that every woman I've ever met or fallen in love with was either a sociopath or a gold digger.** This part is a bit "wordy" I'd say. If you can rewrite that part: "According to you every woman I've ever known has been bad for me."

I get the feeling that she is in love with him herself and that is why she puts down the other women in his life.
