Marriage between a man and a woman is the union that all of Shakespeare's comedies work toward. In order to achieve such a union, the characters in Two Gentlemen of Verona must overcome several obstacles – disagreeable parents, the fickleness of romance, love triangles, deception, and betrayal. Looked at from another angle, however, the pursuit of marriage in the play is the major obstacle standing in the way of male friendship. Although the play ends in the promise of a double wedding, it's not clear whether or not marriage between a man and a woman ever trumps male friendship as the most important human bond.
Although Two Gentlemen promises a double wedding at the end of Act 5, Scene 4, the play also leaves us wondering if Proteus and Valentine will value their marriages as much as they honor their friendship with each other.
Although Julia is ashamed about cross-dressing, her social impropriety is excusable because Julia's actions are in the interest of her getting married.
