You can file complaint of rape with your local police station. 

If you wish to file the complaint of rape against him then it should be proven that since the beginning of the relationship the boy had the intention of using the girl for physical pleasure. If sexual relations were a part of the love between then which later turned sour then it is a different case and not rape under section 375 of IPC, 1860.
