Maybe it's not popular to say it, but I will say it.
Women have problems with dating and sex. And they are tough problems.
But they're not your problems.
Let me explain.
Take your average woman. She's a 6 in attractiveness -- attractive enough to get a male 7 as a boyfriend. She's also attractive enough to get male 9s and the occasional 10 for sex, but getting commitment from one of them is never going to happen. Come on guys, you know these women. You know 25 of them in real life and you go to school or work with at least 10 of them.
She's got a tough row to hoe, a needle that is very, very difficult to thread. She has to find a man she's attracted to and who is dominant and confident, able and willing to support her and sire/father her children. She has to find a man whose clothes she wants to rip off and whose cock she wants to suck twice a day; but who she's also willing to pad around an apartment with in her fuzzy slippers and sweats. She has to find a man she really, really wants sex with; but the catch is that the man also has to be one who really, really wants to keep her long term.
Her prime problem is that almost all the time, she can find men who fit one bill or the other, but not both. Most of the men she can find are either (1) hot but don't want to stick around after they fuck her a few times; or (2) want to be her boyfriend and will offer a relationship; but she doesn't want to fuck them at all because it would be like fucking her brother or her bestie.
She's in a tough spot.
But... and pay attention here. All that is not your problem.
Society and the culture tells you it is your problem. You have to offer yourself up to be her Boyfriend, because that's how you're going to get sex. Society tells you this is your problem because our hypothetical girl is Not Happy, and it is men's job to Make Her Happy. What's more, you're told that if you Make Her Happy then She Will Make You Happy ("happy" being you will get your dick wet).
Well, no. No, being a Boyfriend will not Make Her Happy. You undertaking herculean effort to satisfy her will just make her less happy. You beta boyfriends don't enrapture her with joy; you just piss her off.
Stop trying to solve your dating/sexual problems by taking on and trying to solve HER problems. Her problems are not your problem to solve.
Men, YOUR dating/sexual problems will be well on the way to being solved when you focus on yourselves, your wants, needs, hopes, dreams and desires. Your dating/sexual problem is that you are not awesome and your lives aren't what you want them to be. You're overweight, you don't eat well, and you don't take care of yourself. You don't exercise, you don't take care of your body and you don't dress well. You don't look and feel your best. You don't like your job or you're not all that good at your job. You don't have anything in your life you really enjoy being or doing, just for you.
You don't need to be nicer; you need to hit the gym. You don't need a girlfriend; you need more men around you to sharpen and hone you. You don't need to spend time figuring out how to be what she wants; you need to spend more time deciding who you are. You don't need to spend money on her; you need to get some better clothes and a haircut.
Her problems are not YOUR problems. Let her figure out that Chad's not coming back. Let her figure out how to get commitment from a suitable man. YOU need to figure out how to be the most awesome man you can be. When you are, then you'll be the one who decides on commitment or not; you'll decide how and when and where your resources are best allotted.
EDIT Good discussion on what many women's dating and romantic life problems are. I think it's great we as men can identify them. We can even talk about who's got it worse, if you want to, I guess. I can empathize with women on that. I can put myself in their shoes and say "yeah, they've got it pretty bad in that respect. I can see how that would cause a woman a lot of strife and frustration."
But the thing is, it's not my problem to solve. And it isn't yours either. Identify it. Mull it over, empathize if you want. But don't try to fix it, solve it, resolve it, change it, alleviate it, or wish it weren't so. Just don't. Because you can't alleviate it one bit. You cannot change it. Wishing it away is totally ineffective. The ONLY thing you can do is to get better yourself.
