Heard about Don Quixote? [link] Basically he's read too much stories, and his view of the world is... seriously flawed. I think you could probably learn something, but to be an expert one needs to practice, something which you can't do by just reading. At least unless you're seriously altered/high.
As with all genre-savviness, outside your genre you're still a no-one, and whatever you read is likely not "examples from real life" as a genre.
No, it wouldn't work. I have a friend (he's a guy) who thinks that reading girls' books will help him understand girls better (he doesn't discriminate which books he reads, he reads EVERYTHING). The argument I used for him is the same I will use here, with you:
What happens in stories are just that: stories. They're not real. These sort of things don't happen in real life. The author's purpose is to make money and, in relation to romances, to make readers feel good about what they have read. Things don't always turn out so happily. If you read too many romance books, you'll forget what is real and what isn't in the world of dating, and you'll end up worse than before. By reading so many of those books, you'll get sucked into their fake world and when you finally see the reality, it'll be worse for you than it would have otherwise been.
I think by reading a lot of romance, you can at least make a difference of what's real, and what's not. Because it's fiction, you can fairly say, it's not ever going to happen to a regular girl or guy (nevertheless, that's exactly what happens in the books). There is some wisdom in flimsy romance books though, which you can use in everyday life. How the people on those books, who are said to read that exact same kind of books, can still be like "oh, I had no idea that's what will/can happen", is a mystery though. Because I'm 21, and the girls in those books are about 30, and must have read even more books than I have, and still, they don't get it. But it's a book, right?
