Japanese wife's real feelings: I did not wish to be unfair but my husband’s friend proposed to me to be his bride

Here, what we have is a Japanese wife who finds herself with a very hard to make decision. Finally, her husband’s friend invites her to his wedding, which is bad news for the couple because a ‘friend’ is usually more than a friend to the lady of the house. As to the wedding, the wife cannot decide whether or not to go she is concerned with what the husband might say.
