That's an interesting article, and an interesting premise, and it kind of makes sense to me. However, I also have to note that has not been my experience. I have yet to date a girl long term and have her lose interest in sex. I've heard of it though, so it can happen.
You know, the long term relationships that I've been in, unfortunately, that has been the case. I've been married twice and that has been the bulk of my adult life. Yea, I know, two time idiot but you know, I got stupid each time. You have a kid with this person, and bam, you're done now. Kids take center stage, they should for the most part, but the relationship has to be preserved. Both times, either the crazy woman or the kids take center stage and the relationship takes a beating. By the time you realize what is going on and really admit it to yourself, you're in too deep and they know it. Crazy woman or not, they all know how to manipulate. If you are a man with a solid career, you're always going to have more skin in the game than they do. Most men I know over the years have made more than their wives, so if you do, and don't have an air tight prenup in place, you're going to get fed to the dogs in the US. Alimony, even if it doesn't last forever, is going to last at least a couple of years. Child support, that lasts to at least 18 these days, so you've got bare minimum, at least a decade or more of payments that amount to at least a couple of grand a month. Me, I'd be on the hook for probably 3-4k a month, maybe more, depending on the judge. So if she gets a couple grand a month, plus 3500 for the kids, you're looking at around 5-6 a month for her and the kids. She knows that, she does. She gets a part time job, now she might be making as much as or more than you. I can't afford to run two households like I currently have and she knows it. Tough to not expect someone to take advantage of a situation when they can. Look at it from her perspective. Hey, I can get the kids, the house, the car(s), money and now the bad boy too? Why the h*ll am I still hanging around here. I've got mr. responsibility to take care of me and the kids and I get the bad boy too? This is a win, win for her. Tough to keep the vag juices flowing in that environment. It's like making the man the unic, chop off his balls and make him your servant.
