I'm not going to say Hollywood does or does not know this, that and the other. What I can tell you is that I had a friend (a female, of course) who absolutely did everything you listed in your post and then some. Unfortunately she had a direct hand in a breakup of mine and then she had an even bigger hand in the reconciliation which actually ended up being the biggest mistake of my life in terms of relationship decisions. Looking back I don't know why on earth I listened to her and further I don't know why I didn't tell her to f v c k off waaaaay earlier than I did. She is the biggest and most intrusive meddler I have ever met in my life. I was pretty much convinced that she has some emotional problems.
My point is that just because you have not experienced something doesn't mean it doesn't exist. Im not saying this type of woman is typical (I don't believe it is) but they do exist!

I talk about it only with my best friend (we're both men), not all of them. We don't get overly sentimental, though. And we've never been in a Hollywood situation. You know, like me wearing an earpiece during a date so that he can tell me what to say.
