Homework or not, i'll give you my thoughts.
First, 30th of this month, my wife and I will have been married thirty years.
Marriage is a lifelong committment to each other, it established a stable envirement, (mostly), to bring up children.
Nowadays, people get married and don't expect it to last, thats wrong, marriage has to be worked at, to create a home and a loving envirement.
Yes, arguements happen, bound to, but you work it out, not as now, seek divorce at the first sign of discord, and even though I don't believe in co-habiting, I accept it happens, but its easier to walk away from, with disasterous results for any children there may be.
