IMO, flirting is mostly about making the other person feel special in a sort of sexual way. NOT overtly. Well, maybe sometimes-LOL. Blatant flirt: H and I were drinking wine the other night. I said "Mmmm, has a nice, sort of woody finish." He said "I got your 'woody finish' right here. <wink>" Subtle flirts are basically non-verbal. Brushing up against someone. The sort of 'coy' look. Licking your lips. Touching/playing with your hair. Gently touching someone's arm when making a point. Listen for anything that could have a double entendre and run with it.
Most men want admiration of some sort. Which is what the OW gives them. So, find something you can admire. "H, that is a huge classload-I'm impressed at how much you took on and know that this semester you'll do fab. Muwahh!!" LOL I don't know how you would word it for your husband, but think of stuff you admire and then when the opportunity presents itself, let him know.
You might want to read the 5 Love Languages to find out the best way to show your H love. He may needs Words of Affirmation or it could be Acts of Service or Physical Touch. Speak to him in a way he will *feel* your love.
You ALSO may want to invest in a set of DB coaching sessions with Jody. She's great. Can't say enough good things about her.
