I was arrested but the officer never read me my rights. Why?

There is a common misconception by the general public that everyone who is arrested MUST be read their Miranda rights. Not true. If an officer does not ask the arrestee incriminating questions about the alleged crime, there is no requirement for Miranda. It gets very tricky, but there are many instances when people are arrested and not advised of their legal rights, especially by the officer in the field. A common example is an arrest for driving on a suspended driver's license. The fact that the computer records show that the license is suspended is prima facia evidence of the violation, so the officer has no need to question the individual for verification.
