My girlfriend and I were watching American dad ( dont judge ) and in this episode Stan goes blind to avoid looking at his now "unattractive" wife. At one point the wife says to him, you're a better lover now that you're blind. Now my partner turns to me and says maybe I should go blind too so I can be a better lover and laughs. I questioned what she meant and got upset. Her response : it's just a joke, I was quoting the show. 

Am I overreacting? I feel stupid but she says things like this all the time. Always with an excuse or a " I didn't mean it like that".
