Divorce?

A friend of mine a few months ago discussed with me his marital situation and his life issues with his wife. I tried to advise him in a very supportive way and tried to keep their relationship as good as it could be. He was somehow lost in his way & he was looking at it in a way that maybe his relationship & his marriage was the problem. I knew his wife very well & actually she was a very supportive woman and a very lovely wife for him within all the years I'd seen their life. In the beginning of their relationship things were not so easy for him financially and she was one of the best who could handle the time and stay beside him with support & working with him in a company. At this time, it's not too easy to find a girl who can handle this situation in Tehran at the beginning of a marriage. They usually expect too much; but she did not.
Now years have gone & he does not remember. The only thing in his mind, is now a better lifestyle and more money and new discoveries which he does not remember he could not achieve even this much, without the support of a young lady, like his wife!

I don't know what to tell him. I heard he's asked for divorce!
