Hi, my biological mom married a man when I was 18. He was 25 at that time. I did not meet my mom and this man until 39, as an adult. What relationship is this man to me? Obviously, he is not my step-father, as he did not raise me, and I only met him later on, as a mature adult.
Also, what do I refer to this couple as? I reluctantly introduce them as "my parents", but that doesn't seem right, since the man is like a stranger to me, and only 7 years older than me.
