I'm divorced, so yes, I believe it's OK.
However, I got married too fast, too young, and I didn't listen to a thing anyone said. If I had a brain back then, I would have never married him, and that would mean I'd never have divorced him.
As it was, I found out that friends (the one's who warned me), placed bets on my marriage - most were in the couple month range, very few, if any went over a year - I beat em all! I filed the day after my one year anniversary.
I think it's reasonable to consider divorce for any one of the three A's - addiction, abuse or adultery. My ex was an expert at all three, along with a serious compulsive lying problem. I still stuck it out....and it ended up costing me $150,000 and my credit. I tried to work with him, I got counseling (because he said it was my fault ), I got the books, I did what I could. Now I look back, and I can't believe it.
But divorce for boredom, lack of "love", silly arguments etc? Not that cool, but hey, that's life here now. I'm married again, but then we have never had the problems I had with my first ex.
So, there are times, where it is necessary for a divorce, but I think that the entire sanctity of marriage is being destroyed by high divorce rates. People should make a stronger effort to fix the problems than opt for divorce
