I have a married friend and we kind of flirt a little but absolutely nothing has ever happened between us. He always talks and smiles and looks at me and kind of follows me around but when his wife is around he freezes up and gets this scared to death look on his face. Why? Nothing has went on between us. The other day a bunch of us went to an amusement park. When he would speak to me his wife would look at him like she was going to choke him. I don't get it. The flirting is innocent and she never even sees it. Why does he act so weird?
