Proverbs is very pro-family. Of course, there aren't any books in the Bible that are like, "Families are just the worst"—though it definitely depicts its fair share of highly unpleasant families.
At any rate, Proverbs sees the family as being pretty essential. This is part of why it lobbies so hard against adultery. Just as a person needs to be super-focused on one God, his or her life should also be super-focused on one family and one spouse (one's own). The wisdom of parents and revered elders is a persistent theme in Proverbs—children are supposed to receive this wisdom, and ought to be disciplined until they're capable of it. Craving novelty sets you on the path towards adultery and ruin.
