Cool girl

So I, like many, have recently gone to see Gone Girl, the creepy mystery thriller about a batshit crazy wife who frames her husband for murder, but then changes her mind and realizes they are soulmates, based on the fact that he knew exactly what to say to make her come back so he could kill her.
All sarcasm aside, great movie. Even better book. The difference between the movie and the book is that the book ends off somewhat different. At the end of the book, Amy asks Nick why he is so wonderful to her. Nick responds that it is because he feels sorry for her, because everyday she has to wake up and be her. Amy then says she wishes he didn't say that, and that she's glad she got the last word. She's earned it.
What does this ending mean?
In my opinion, it means that she is being retributive God again, and she must punish him for what he's said. She can either do this by killing him, and silencing him, or by killing herself, and the only thing he truly loves, his baby. I think the latter makes more sense in how fucked up she is, but then again she loves herself too much to kill herself. She doesn't think she deserves it.
But the really messed up thing is that all of this happened because of what? Because of marriage, or rather, the crazy shit people do to get someone to like them. This movie actually touches on both men and women changing themselves to be 'worthy' of the other person, but as I am a girl, I will speak to it from my girl standpoint.
By the by, isn't it kind of weird how a girl can call herself a girl no problem, but a guy would never call himself a 'boy'. I guess because girls like to feel like a young dumb innocent child? There's something pedophilic about it.
Back to the matter at hand. Have you ever seen that Friends episode, where Rachael doesn't know how to get that guy Joshua's attention and she tries everything to get him to like her? She was trying to be the 'cool girl'. The fantasy girl that all men drool over. Who is this girl? Well, she basically molds herself to whatever you want her to be. She's funny and witty, but never tries too hard at first, that's just desperate. She's independent and gives you all the space you need, no clinginess here. She let's you do inconsiderate dumb shit without so much as batting an eye lash, no naggy bitch necessary. She pretends she's not at all hurt when you act indifferent and don't return her love. Because its ok, she's cool.

Well, this bitch is whack.
 I know, because I have tried to be this girl. I thought that's the natural thing you have to do in order to get a guy to like you; become a version of you that he would like. What an idiot. No.
Girls, ladies, bitches, for the love of God, stop doing this shit. Stop the madness.
You do not talk like a sexy kitten and naturally flip your hair 'coincidentally' as he catches a glimpse of you. You are not just fine with the fact that he treats you like an option all the time. Like you have to be the 'cool girl' to keep his attention.
I know, because I've been with a guy like that, and I've been with the real deal.

The real deal is really into YOU, and I mean the real you. He accepts that you're not always going to be flirty and hilarious and chill beyond belief, but at the same time, he has a way of naturally bringing the best side out of you. He makes you want to have a fun personality, because you are genuinely having fun. He is there for you when you are having an off day and being a bitch sometimes, and doesn't just attribute it to the fact that you are a woman and that's how they all act. In return, you understand when he's being a pissy brat when he's sick, or taking an hour to choose one damn movie to watch, because you're into him for real, and at the end of the day, no matter how much you push each other's buttons, life is always better with him in it. So go for that guy, trust me. Don't nag about every damn thing, but if something really hurt you, tell him, in an adult way. If he tries to understand you and find a solution to the problem, instead of being shocked that the cool girl facade wore off, he's good. And if you can genuinely be yourself around him, flaws and all, you're good. And if you're not, well, I guess all the cool kids are doing it.
