Guide to Dealing With Opposite Sex Friendships in Marriage: Reasons Why People Ditch Their Friends When They Get Married: And How to Deal With Opposite Sex Friendship After Marriage

Description

1962 Roman Rite nuptial blessing mentions the importance of friendships in marriage:

May the peace of Christ dwell always in your hearts and in your home; may you have true friends to stand by you, both in joy and in sorrow. May you be ready with help and consolation for all those who come to you in need; and may the blessings promised to the compassionate descend in abundance on your house.

This is the only book I've seen on the topic of opposite- (or same-sex) friendships for marrieds.

cf. male-female friendships

There is a general notion that most married people ditch their friends immediately after getting married. Whether they do it knowingly or unknowingly, such an assumption is only a little valid. This book explains some of the reasons why such happens and how to maintain friendships after marriage. In maintaining this friendship, the question that arises is: can a married person have a friendship with the opposite sex? This book, while pointing out the negative implications of opposite-sex friendship on marriage, highlights ways to maintain a healthy friendship with the opposite sex.
