When Your Partner Gains Weight - Do You Tell?

Smart men know that the answer to the question "Does this make me look fat?" is never, ever "yes."

Still, let's say the healthy and fit person you're dating or married to suddenly starts to pack on the pounds. Is it ever acceptable to tell your loved ones they're getting fat?

I ask because of this clip from Tyra. Mr. I-Just-Want-You-To-Be-Healthy tries to convince his girl that he loves her for who she is, he just wants her to lose weight so she'll quit whining about it. But his true motives are revealed when he basically tells her if she doesn't lose weight, he'll be forced to cheat on her.

Niiiice.

Still, let's say you're a more conscientious valentine, the kind who really is just concerned about your lover's health. Is a heart-to-heart talk ever acceptable ... or even helpful? Or is it better to health up your own habits and hope that your love will join you in your efforts? What do you think?
