because you are a boring person?
You can not change a person unless they want to change. He may not be as "boring " as you think. Look, to self before deciding "who" a person is in life.
A not entertaining person
A person can ask others if they think they are boring. They can also watch how others react during their day to day conversations. If they see a lot of yawning or straying away, that might mean that the person they are talking to finds them boring.

Don't be boring! He wouldn't say you're boring if you were anything but boring. Additionally; learning to properly use the English language, either written or spoken, will greatly help in your quest to have a conversation with this person; assuming their first language is English as well. From the looks of your question though, this person may be mistaking your "anything but boring" persona with someone of lower intelligence or lacking in education.
