What is the ratio to woman dumping their partner and vice versa. (I
suspect that more women dump men :)

I've heard that, in the UK, over 60% of women sue for divorce.

What I should have said is that, in divorce cases, over 60% are instigated by women.

The other 40% are also instigated by women: advertently cleverly or
inadvertently, but both resulting in the man's suing for divorce.

They may instigate more divorces, but they still only get half of a man's assets.

See - it's a fair system.

Dump equals d i v o r c e ?    MOT

Confucius says that, instead of getting married, it is better (and
cheaper) for a man to find a woman he hates and then to buy her a
house.

I only know about my countary i.e. India.
A traditional Indian woman never dumps her husband even if he happens
to dump her. Once she is married, she devotes herself totally to her
husband.
So there is no woman dumping a man out here.

In the USA, the figures run closer to  75 - 80% female instigated
divorce, and this has been true since early 80's at least.  In the
overwhelming majority, the other man is on hand before the divorce is
filed, though it is definitely non-PC to say so.  I saw my own sister
pull this stunt twice; once with a 42 year old man when she was 21,
and once with a 21 year old man when she was 42.

I do agree the question does not seem to involve divorce, but all
relationships that end.  I am not an expert on non-divorce endings,
but listening to women at work before retirement, they at least
believe they end most other relationships as well.

So actually -atleast- 80% of woman end a romantic relationship?

Johanka,
The statistic Irlandes mentions suggests that in 75-80% of divorces,
the woman instigates proceedings, not that 80% of marriages end in
divorce.

No, almost 50% end in divorce.
But it's very interesting to see that far more women "dump" men than
the other way around. Then you can ask, why?

dis is the common question askd all over de world........women are
basically designed to pursue a temporary targets...wen they do attain
de targets they go on to the next one....The same rule applies in this
region too...wen women find a men attractive she wants to him....wen
the target is attained she goes for the next handsome guy.....But the
rules don apply to all the gals......

It's very simple: women are NEVER satisfied.

That's the way they're made.

The problem is that they read too many magazines, etc. that fuel their desires.
