Intriguing. I must say you all watch too many soap operas for jumping to the issue of divorce right away.
Now a question that has cropped up. Why are you all making the assumption that the my dear friend is not an understanding husband?
... because he is your friend... not your Husband. you dont know how he is as a husband. there would be alot more friction into their relationships which obviously your friend won't tell you if he is to blame... their life long relationships are much more important than your vaction times...so leave them alone and let them to work on it
