I think no one can make anyone go if they don't want to. What I
don't understand if why men often persist in failing relationships,
often waiting and waiting for the other party to force a split up
simply cos they don't want to be the bad person to trigger the
breakdown of a marriage.
There are many reasons why marriages don't work out, and what you
have described - the insecurity of women - is only one possible
reason.
I think it is equally painful for women to suffer insecurity. And
many men, who 'suffered' at the hands of insecurity, have their
tables turned when they have relationships with independent women
who are not insecure. It is a sad irony that, basically what a lot
of men want is to BE the person a woman thinks about, without
wanting to feel the inconvenience and pressure of being missed.
Unfortunately marriage is about commitment AND an obligation to
each other, whether it is about fidelity or not.
Without commitment, there neednt be a marriage n the first place, a
casual relationship is good enough.
