What is the theme in Maurice by E. M. Forster?

Friendship is another theme in the story. Due to his uncommon sexual desires, Maurice cuts himself off from other boys. Maurice has few friends because he always feels that he has to hide his true nature and keep distant from other people his own age. While at Cambridge, Maurice finds a group of boys with whom he can be more like himself. Among these men is Durham, his first love. Maurice is shocked when Durham first announces his feelings for Maurice, nearly ending their relationship before it can begin. However, Maurice finally tells Durham the truth about his feelings and convinces him of the importance of their relationship.
