My Secret

I work in the service desk area of a grocery store and I meet and see a lot of people everyday, some are repeat customers. I am not attractive by any means, but I feel like some of the men flirt a little with me and I honestly feel really flattered and I unconsciously flirt back. I secretly like the attention, but I have a boyfriend and he gives me all his attention, but there's not a spark anymore. I've brought up that I don't feel special anymore and everything and he just kind of brushes it off. My boyfriend is the love of my life, and I feel terrible if a guy even looks in my direction. I guess it's my own dirty secret, I don't think anyone else has this secret.
