What has become of this Holy Institution '..... Marriage?

What is going on in the world these days?  I am no expect in marriages but I used to think marriage was sacred and was instituted by God.  Is it because man has become so intolerant or is it a change in our value system? Many couples these days take the easy way out - divorce when trouble shows up.  This does not affect only non - believers, it affects us,  christians as well.  I know this issue is very sensitive, but if our reason for being here is to honestly help one another, I would be grateful if those who have survived in their marriages would share with us, how they manage.  I hope this discussion will not be of beneffit to only me, but also to others who are struggling to survive.

On the other hand, if there have been earlier discussions on this topic, I would be grateful  to receive any references to such discussions.

Thanks and God bless.
