Explains why my ex-husband would resort to infantile pouting when we'd go to celebrate something I did (some accomplishment) with friends. He'd sit there like a miserable sack of sh*t, refusing to engage in the meal. Sipping on his glass of water while everyone else ate. Wouldn't order anything, just sulk. No explanation at all. At the time, I was bewildered and frustrated. I'd just been offered a writing job, was out with friends to celebrate, and his mood shifted from loving partner to petulant child. Totally ruined the night - I guess because he wasn't center of attention. Christ. What a baby.
