... Book in which it is question of respect for the other, learning to get out of a conflict, also get to know, to know each other and make his (or her) best friend (e) and also and especially watching his qualities rather than its defects, because we may say that nobody is perfect, some people tend to forget.
For men "too nice" I would also recommend "Too nice to be happy" by R. Glover, see my review there too.
