I always make fun of my girlfriend about the way she dresses. She comes from a middle-class family whereas I'm better off than her. We are committed and plan to tie the knot next year. The only glitch is she doesn't take my jokes kindly anymore. Earlier, she used to laugh like hell whenever I pointed out her middle class upbringing in jest. The worst happened last weekend when she threatened to break off if I didn't stop throwing stupid jokes at her expense! Is her behavior normal?
