Sheesh aimeemarie, you sound like my wife, who is beautiful but still has this complex. You must get over it. It gets to the point where that ominous question comes up "Do I look fat in this", and I look, and being honest, say yea or nay. However....if I say yes, it's like "You're lying, what do you know? Now I have to change." Can I say what bullshit? If I wasn't honest with my wife, what sort of man would I be? Strangely enough, when something doesn't look good on her, and I say so, she is very calm and says, "Yeah, you're right. I'll find something else to wear." Go figure.
I suggest that all women learn to distinguish between a true compliment on their looks and a perceived insult. I'll be at The Learning Annex all month attempting to teach this to y'all.
