After that first date, I taught my girlfriend how to play chess.
While we were dating long distance, we chatted on a chess site because it was cheaper than our long distance phone rates (cell phones were not yet the norm, although we both had them).
When we were living together and had different work schedules, I sometimes got frustrated while studying a chess book. She would come home and I would need to put my book away and play her. When she eventually won a game, she lost interest.
It is rare now that she lets me show her my latest tournament win, but she does have a basic understanding of the strategies.
She hates my blitz, despite me telling her I'm not young anymore...
