Hey guys

I am 36 years old and 1′m divorced. My partner is 39years old and has never been married, although he has had long-term relationships. He tends to be secretive and likes time to himself. He says that he will never marry and is not sure if he could live with anyone again. We have been together for four years. Am I wasting my time staying with him? Please Ineed Help on what to do!
