When I was 15, a guy asked me out who had a super crush on my Mom. He admitted it to me during our first date. (My Mom was a high school teacher.) My Dad thought he was a pimply faced dweeb, my Mom thought he was creepy and I quit dating him after the first month..
Glad things worked out well for you. Don't let that be the last time you have a good talk. In relationships, communications should be constant and once in a while it's nice to sit down and have a good long talk about the present and future..
