A theory about understanding the other gender

First of all, note that this is just a theory. I don't, by any means, want to insult anybody with it. If you disagree with these theories, write a comment, criticise me, I'd be absolutely willing to learn.
Also, of course, all the things I say aren't rules that always fit. There are exceptions, of course.

Alright, let's get started.

The main difference is how men and women show their love about each other.
This theory doesn't nessecarily work in homosexual relationships I'm afraid. I might be wrong with that too though.
For the ordinary, average man, the career is directly tied with women. To find that out, you just have to ask some of your male friends or buddies, I heard guys in my former class openly admitting them. They wanted a good, well-paid job and they wanted to have success in it. The cash and the respect is an important reason for that but also, they wanted to be able to impress women and to be able to feed their families.
For many women, a career is important too. But it's not important as in 'without it, I'm a failure to my partner', but 'without it, I'm dependent'. Their career is important for their independance.
That, of course doesn't mean that women care less for boyfriend, husband and family. They just don't mix their care up with their job, their career and reputation. For them, this kind of care is much more emotional. Which can, in extreme cases, lead to a certain paranoia about what they say and how they act.

Let's take a plain argument as an example.
A woman dressed up for a man, he doesn't notice it because he's tired from work. For her, she is showing her care for him by making herself pretty for him, while he can't understand the ruckus. For him, he shows his care for her by putting efford in the work.
This might sound weird, maybe even a sexist but here comes the point: This isn't something concious. It's sub-concious. So many men are like 'It's impossible to understand women'. It's not. Not if you manage to understand this difference and understand that they think similary about men. And vice versa, which is the reason why many men seem to be so ignorant idiots to women.

Tell me what you think about it, more of my retarded ideas will follow.
