he loves me, I think

My loving bf said he'd love me even if I gain 30lbs. What does that even mean?! Is he talking about 30lbs over the average weight of an American women? Or is he talking about 30lbs over the weight I think I should be?

Because if it's the latter, I think I'm already half way there.

I'd probably love me more if HE gained 30lbs only because he's so effing skinny that I feel porky. I have low self-esteem.
