At the time, I was in my 30s and he was in his 50s. I was well aware that he had children who were my age. Likewise, he knew that while I was in high school, he was already married and established in his profession.
My kids make faces and say, "That's so gross!" when I tell them that I was in college when my husband, their step-dad, was in middle school. We get a good laugh out of that! The reality is that I am only five years (almost to the day) older than he is.
