About now, your partner might not feel very attractive. Take her on a date - go to dinner and a movie! Tell her she's beautiful.
Remember back when you started dating. You remember, right? You'd bring your wife flowers, tell her how beautiful she was. Remember that time you brought her lillies and her eyes glinted in the moonlight just so, revealing the life within?
And remember that one time you caught the glint of the Bears game in the corner of her eye while she told you about her day over a bucket of KFC? Yeah, that was last week. Feeling good about yourself? Because let's face it, your wife feels like a whale. And yelling "AAAAOOOOGA" while you lowers herself into a bath tub, well, frankly that doesn't help.
I'm not going to sugar coat this: you're an asshole. Tell your wife she's beautiful. What the hell's wrong with you?
